Is that bolt secured tightly? Both pieces of that cam thingy?

Yeah I tightened that bolt down good. I think it's the arm itself and the springs that rattle.

Just finished installation. Took me a little longer due to being very meticulous about routing the wiring harness. I used a different method of connecting the wires though. I routed my wires all the w

Can't help you with the e-clip size, sorry.

 

I did this mod yesterday...took an hour or so. Hardest part was running the wire over the gas tank next to the frame rail. It was cold out so the wire harness was very stiff and I should have unwrapped it a day before to stretch out.

 

Wire colors are for Sierra SLT Z71 Crew...gray with green stripe and brown with yellow stripe are the correct colors in the drivers door sill.

 

You can use a straight pick to get that snap on cover off over the wires. Hit the side near the seat first, slide the pick in, start from the front and work your way back. Be patient and you'll be fine.

 

I stripped off insulation so I had about 1/8" of an inch of wire exposed. Used the pick to make a hole in the copper strands, snuck the new wire through, braided it up and soldered. Wrapped with electrical tape and buried back inside the harness as far away as the other connection as I could. I cut off about a foot or so but also left excess in the kick paned in case I need to change something down the road. I also used the pick to make a hole in the shift cable boot to sneak the wires through. The grommet used to bring the wires into the cab is the transmission shift cable, not the parking brake.

 

The actuator is loud but I'd rather hear it than guess.

 

Thanks everyone for their help...this post is very informative.

I'm missing the E-clip. Can anyone tell me what size it is so I can get one from the hardware store?

 

Mine was missing as well. I re-installed the original and the company shipped one out that I inatalled a week later. You could take original to size replacement.

So I installed this on Sunday. E-clip is 1/4" and can be found at any hardware store.

For the wiring, I followed the directions in post #98 except that I simply stripped the blue and green wires, tucked them into the plug making sure to put them on the side under compressions when in it's normal position, and then zip tired the wire to the wire bundles at the BCM. No solder, no risk of breaking the wires, completely removable if necessary.

Hi, I joined this forum for the express purpose of thanking MotoMedic for this great write up. Thinks to his DIY post, I just finished installing one of these on my 2015 Silverado 3500 Dually. I will say that if you have a crewcab with a long box, don't waste any of the wire when routing because you have just enough - unless you spool out some of the tailgate wire, which could mess you up if/when you need to remove the tailgate. Pops&Locks should throw their instructions away and pay David to use his write up. It's much better! Thanks.

Installed my pop & lock today on my new 2014 GMC Sierra Crew Cab standard box SLT and it went great. Thank you to Motomedic and all who contributed to this thread. It helped a lot!

 

I decided to go with pressing the unlock on the keyfob twice to unlock the tailgate. Here's the wiring that worked:

- vehicle's fat brown with yellow stripe attached to the green pop & lock wire

- vehicle's fat gray with green stripe attached to the blue pop & lock wire

 

When I was finished, I found that I couldn't lock the tailgate with the key. After investigating, I found the new C-clip was moving with the key, causing the locking mechanism to flip to unlock when I returned the key to 12 o'clock to remove it.

 

The fix: I had to remove the C-clip and re-install it so that the mouth of the C-clip was facing "down" towards the hinge point of the tailgate. Originally I had the mouth of the C-clip facing "up." Hope that helps someone on their install.

 

Thanks again to a great thread.

Got around to finally doing my tailgate lock in between putting a new clutch in the Camaro. Wanted to say thanks to the OP and the guy above for pointing out the two wires to put the lock on second FOB press. That's the way it should be, I say. The unlock switches on the doors operate it, two presses of the remote unlock operate it, and one press of lock on all operate it.

 

I had the wiring done in 10 minutes, it took me a lot longer to prep and run the wire up the chassis. I chose to run my wire inside flex tubing wrapped with electrical tape, similar to factory style. Being up in the North East, anything you can do to keep the salt off stuff is worth it. I ran along the factory harness until I hit the floor grommet and went that route. It's far easier than anything else I saw under there. I re-zipped the wire bundle like it had from the factory. Run the ziptie from the inside under, and when you see the tip on the other side, use small needlenose to pull up on it while you push, you'll get it through. Also I didn't have my good multimeter handy, so I used a cheap one. It was too slow to read 12 volts I think, I saw 5-6v on unlock, and somewhere around -3v on lock. It was a solid connection and operates the tailgate as it should. Tested it at the bundle, at the weather connection, and at the tailgate.

 

I have a full Line-X and bed cover, and I can hear the lock, but it's not disturbing.

 

This is on a 2015 Silverado LTZ Crew Cab Regular Bed. (Z71+Backup camera if that matters..don't think it does.)

 

PS: For a truck with 2,000 miles, it sure does have a disturbing amount of rust already.

Did you have to cut the line x after taking bolts off of the tailgate panel to remove it?

I haven't received my ordered truck yet that is coming with the spray in bedliner so not sure what it exactly looks like.

I didn't get a factory spray, my dealership hired a local Line-X contractor. They pulled the access panel and sprayed it off the truck. Worth it when I went to do this. It didn't even stick after the bolts were taken out.

 

If they spray the bolts, make the dealership fix it. Nobody should expect that. As for cutting around the panel, can't really say.

Ok thanks guess I'll have to wait and see how the factory does it. Hopefully they do it like your guy did, would make it a lot easier for me.

Can't imagine the factory would want to put the service techs through that nonsense if the tailgate needed servicing.

      Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.

      The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts.

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.

      Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.

      Multigate electrical problem

      By Another JR · Posted

      The recall is for exactly this issue - those drain holes combined with the limited environmental capability of the tailgate electronics card inside the tailgate were a problem. The “safety issue” was the potential for the tailgate to spontaneously open, but all kinds of tailgate misbehavior can occur from water contamination of that control card.    There is no real fix yet. The initial recall just disabled the tailgate. Later, when parts became available, they would replace bad parts with new parts of the same bad design. My dealer is going nuts because the few times I let them get their hands on my truck, my tailgate is off due to a slide-in camper installation. They really want to cut my tailgate wires, but I won’t give them the chance. I will let them get their dirty hands on it when a real fix (redesign) is available.  My tailgate, which works just fine with sealant plugging the drain holes, will remain safe in a dry storage crate until then.
