The upfitters manual (800+pages- downloadable pdf) has all the connectors, pin numbers , circuit number, terminal types that you will need. It also helps to have a spare wire harness to look at outside the vehicle.

Once you have your 4 wires with correct terminals on each end, (2 per side), you need to run them from the mirror connector along harness to large 41 pin door connector, unlock connector (mine was pink) with a small screwdriver, push the 2 terminals into place(#3) on mine). Wrap, tie, tape as needed, push large connector back into body connector..no connection or splicing anywhere under dash. Lastly run short ground jumper at mirror connector.

Note that the 4 wires needed are roughly 16" long each. I can get a more precise measurement if someone is interested.

Your no splicing method sounds bad ass. I would be interested in more detailed pics for when I do my DL3 conversion.

That clear a lot up for me thanks. I have to order the switch since the one I had is the wrong part since it came from an Ltz with memory functions.

Just completed my upgrade to the DL3 power fold mirrors. This forum and the upfitter's manual were a huge help! All original features plus the power fold, blinkers and puddle lights work perfect. No factory wires spliced, tapped or cut into. I have a 2015 LT, dbl cab, z71. Keep in mind that this write up applies to my 2015 truck. The 2 circuits needed on each side were already in place to my door connector, just not in my door harnesses. This may not be the case for all models/years.

Here is a quick overview of my upgrade.

1.Purchased dl3 mirrors with wire harnesses from a forum member for $300 shipped. Thanks Gordon.

2. Purchased switch gm pn 23154702. from gmpartsheadquarters.com.

3.Cannibalized one of the spare harnesses & removed 4 wires with terminals complete plus 2 short wires for the ground jumper on mirror connector #510/610. A bit of a job, but well worth it in order to eliminate the need to splice into any of the factory wiring on the truck.

4. Removed door panels and upper window trim panel. Highly recommend watching some of the youtube videos on this procedure. Get a set of the plastic body panel tools. They are inexpensive and very helpful.

5. Fished 2 wires with terminals (from spare harness) through from door connector X500/X600 to mirror connect X510/X610. Unlocked connector locks , inserted pin terminals into each connector , closed connect locks. One wire is for puddle lamp supply (circuit5996), other is for turn signal (circuit1314/1315). Wire tie and tape wrap neatly to factory harness. This is the most time consuming, just be patient and take your time.

6. Put short ground jumper into X510/X610 mirror connector pin 5 location and jump to ground circuit 1150/1250 pin 11. This is ground for puddle lamp.

7. Install mirrors, my torque setting was 5.5 ft lbs. Install door and trim panels. That's it.

One observation that I did not see mentioned in this topic...The puddle lights are tied to the day/night sensor and only get bright at night when the unlock button is pushed on key fob, then they are nice and bright. Don't panic if they don't seem to work in the daylight. If anyone would like more detail or pictures just let me know.

 

Please help me understand. I have a 2015 silverado lt with DL8. If I buy DL3 mirrors and matching door harnesses do I still need to add 4 additional wires to make the signals and puddle lights? I would think they would be included in the new dl3 door harness right?

You can indeed use the wire harness that came with the DL3 mirrors in your LT, but you will need to modify them. They have additional wires that send reference voltage and communicate with the memory module that your LT probably does not have. Unless you cut/disconect the additional circuits, some of your mirror control features will not work. Others in this forum have also document this. I think its less trouble to add the 2 wires and ground jumper to the original Lt harness.

So I finally received the right switch part #23154702. Powerfold heat and has full motion. Googled for hours on end to find a pic or reference as to what wires are what and go where but didn't find any solid info to make my puddles and blinkers work. I'm pretty good with wiring and figuring out what to do but this here has me stumped and I don't want to just guess till I get it right on a $45k truck. The info above makes sense to me and is what I want to do but again can't find even a diagram for pins or wire colors

Hello everyone! I'm a long time Tahoe/Suburban owner but new Silverado owner. Picked up a 2016 Black LT, Texas Edition, 5.3, Crew Cab. Very excited to stumble on this forum. My truck is at the dealer now getting the spray on liner and windows tinted.

 

My question - Has anyone done this on a 2016? From the numerous E posts I've read, it looks like it might be the same harness and switch situation? When I dropped my truck off, there was an LTZ being worked on and saw the these mirrors I want.

I am sorry for bringing back an old topic. I am hoping one of you could help me out.

My truck is a Chevy Silverado LT late 2015 build.

 

I picked up a set of new takeoff DL3 mirrors with both door harness’s. Just to be clear I only want the mirrors to have:

1) full power motion controls – up/down & left/right

2) heated mirrors

3) turn signals

4) power fold in & out.

5) Puddle lamp if possible.

I do not want or need auto dimming, auto tilt or object detection.

I installed the mirrors over the weekend & I used my stock DL8 mirror harness's in both my driver and passenger doors with the power fold switch #23154702.

On both mirrors I have:

1) full power motion controls up & down/left & right

2) heated mirrors

3) power fold in & out. (only by using door switch #23154702) *no fob control*

 

I did not have time to install the DL3 door harness’s. My real question is, what is my best/easiest option for getting Turn signal and Puddle lamps to work?

 

1) Could I just install the DL3 harness’s and everything will work?

2) Or Shouldn't I be able to unpin#'s 2, 15&16 from the DL3 harness and make everything I want work like power fold in&out/ heating/ full motion/ puddle lamp and turn signal all function rather than taking wires from the DL3 harness and adding them to the DL3 Harness?

https://www.dropbox.com/s/nb4mmlirzv6pb7o/driver%20door%20harness.png?dl=0

3) Should I keep my DL8 harness and take apart the DL3 harness wires I need and add them to the DL8 harness?

I am confused as to why the extra wires on the DL3 harness causes other features to fail? I.E. - the loss of power control for Drivers mirror left/right and all power features to passenger mirror?

Take a look at this How To I just created. I just finished this upgrade and ran into the same issues you did. The reason why you lose functionality is because the harness you got is pinned out for the seat memory switch that you don't have. There is a circuit that runs through the seat memory switch. I even went down the path of adding the seat memory switch but the door panel trim connector doesn't have the pins loaded there either.

 

I asked the same questions - should i keep DL8 harness and add turn signal and puddle, or keep DL3 harness and add the power fold, left/right control on drivers, up/down-left/right on passengers.

 

I ended up using the DL3 harness and harvesting pins from the DL8 harness.

 

Good Luck!

Glad I could help. This forum has been a tremendous help for me, so when it was my turn to tackle this, I wanted to make sure I documented everything, and help others with this.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Thanks - I wasn't quite caffeinated this morning. 2:1 makes sense, turning the crankshaft 360 degrees will turn the cam 180 degrees, and had I done that, the cam's dot would be at 6 and the crank's at 12 again.   I went ahead and took the sprocket off anyway, aligned everything dot-to-dot including the balance shaft just for s&g. I'm glad I did because I discovered no Loctite on the timing sprocket bolts. Maybe it's not required, but at only 20 ft-lb torque spec, those bolts aren't in there very tight. Cleaned and reassembled with some thread locker and torqued.   A general observation: Less is more with RTV. If a little doesn't stop a leak, a LOT probably won't, either. RTV is thinly veiled revenge, in a tube...

      The timing marks are ok, that is #1, you can turn it over until they line up and it won't change anything, the crankshaft turns twice for every camshaft revolution, I have always set up SB Chevs as your pic shows using a straight edge

      Wow I'm in a pickle. (Broke down truck) and a story.

      Someone's been here before.... There is a receipt for a 3-piece timing set, purchased earlier this year.   Is this picture something, or, nothing?   I have the timing cover off and my crank is perfectly TDC and the keyed gear's locating mark is dead on 12 o'clock.   The cam gear locating mark is also at 12 o'clock. Now, I'm not an expert, but all the install guides say the two locating marks should meet and be perfectly aligned when installing a timing set. The mark on the crank should be dead on 12:00 and the cam gear's mark should be dead on 6:00, and both marks should be perfectly vertically aligned.   I believe the timing gear is keyed or has a dowel that ensures it can only be installed on the cam in one position, so I have to believe the cam is out of phase somehow. At the very least, with a triangular bolt pattern, it can only be installed in one of 3 different positions.   Before I pulled the front cover, the truck was running alright, no service engine soon lights except an occasional P0172 / rich condition. Timing -16 timing at idle (should be +16), and total -35% fuel trim, two conditions I haven't been able to figure out.   In related news, my injector tested pretty well, wasn't leaking, but I had it rebuilt anyway, and it's on it's way back to me.         Along with this discovery, the good and bad:   Good: The oil pan seal appears undamaged.   Bad: -The timing cover has been reused, and the positioning dowels have been broken. That could explain some of the leaking. -Some kind of white paste or grease was used to try to seal the oil pan seal and timing cover (since wiped off..). -Then, someone globbed silicone all over the front of the cover and also buried the ckp sensor in it. But, they didn't put any inside the cover or use RTV to try to seal the oil pan seal with the timing cover (good).

      PF63 Oil Filters Going Away?

      By Grumpy Bear · Posted

      The guy that owns K&P filters last I checked in with him has over 300,000 miles on his Dodge base Hemi using his own 35 micron absolute stainless mesh filter from its first oil change.    The GM study I've posted a dozen times shows the relationship in engine life based in multiples of base units, not miles or years. That is the base unit is the number of miles the motor ran using the reference filter efficiency.    The above two paragraphs dismantle anecdotal arguments IF one changes oil often enough to prevent particle formation and the motor is in otherwise good shape. That is not full of silica (no air filter) or suffering a metallurgical issue that is not part of the lubrication discussion. Poor heat treat in example.   Data from UOA's I've reviewed from more than a few engines can show remarkably broad variations in oil cleanliness using the exact same filter over the course of an engines life.     Lastly there is the common sense of it. Wear debris WILL circulate the engine BEFORE it ever sees a filter in route to that filter and WILL harm the pump which NEVER sees filtered oil.    Alpha question then becomes, given the facts, how long do you believe is a reasonable service life from a vehicle you are certain you will not pass down? That is the junk yard will be it's resting place when you're done with it? (the moral issue most don't care about).    Omega question is then how diligent are you prepared to be in general mechanical, air & oil maintenance? Preventing particulates and keeping them sufficiently dilute; preventing the precursors from generation, amalgamation and precipitation.    If I get a good look at the engine bay of a vehicle I have a fair idea of the owners commitment to the inside of the power train. That 30 micron WIX is still more efficient than a sieve.

      It also depends on what criteria someone is using for “best” when talking filters.  Are we going off best efficiency?   Best quality/QC?  Etc. because the two may not mutually exclusive.
