It's a purplish pink wire with a stripe if I recall correctly. It's also very thin since it only carries current for the parking lamps-I think it was 20 awg. It's probably easier to identify it as the wire that connects to the fat yellow wire on the other side of the plug (the headlight plug). Anyways I cut the wire, joined it with an 18 awg wire to signal my relay using a butt splice and heat shrink.

 

I should add you only need 1 relay if you have an HID kit as most HID kits are single input for signal. Because I'm switching the signal wire going to the HID relays I'm not really load carrying so I'm not affecting voltage drop by using one relay/circuit.

So I can get this through my head......lol. From the relay, I'm grounding 85, t off of parking lamp POS wire to 86 and then cut Low beam wire and have one end on 87 then the other on 30.......correct? I'll have to use two relays, I guess, as I'm not using HIDs. Thanks!

86 parking light

85 ground

87 low beam

30 low beam

 

87a (if applicable-not used)

 

Yes, two relays one for each side.

Appreciate it!

If G (wire) in the headlight plug runs the DRLs, couldn't you install a diode in that wire to render them off all the time..........or (cut the wire and tape it up, if you desire)....?

 

Also, the wiring manual shows G to be the wire on both plugs (right/left)....

This is what I was wondering, anyone try it? Guessing too simple or too good to be true.

I didn't have time to read this but I'm pretty positive my DRL turn off on my Silverado if I just turn off the automatic headlights function.

Oh, maybe that's it. I'll have to check my reflection next time I can to see if they are on when auto is off. Didn't think about that.

I liked the DRL's until I got HID's. It just adds too many cycles to the ballasts and bulbs. I also found it annoying they went off in park. Imagine being in a drive thru or long line and going in and out of park. I'm looking for a clean way to possibly add Osram LED DRL's to my truck.

I checked my reflection behind another vehicle, and when I turn off my auto lights my DRL are NOT on. I have a 2015

They are depended on where the vehicle was sold. Canadian ones definitely wont turn off. there is DRL forced on during day time, mains are forced on during night.

I just completed the relay mod yesterday. It cost me all of $20 for a waterproof relay. I tapped into the parking light power and used it to signal the relay. The relay simply completes or opens the circuit between my factory low beam signal and the HID kit relays. Everything now works like stock Auto, Off, Parking, Parking & Headlights, the only difference is that the DRL's never come on.

 

The best part is without DRL's I've now been able to get rid of my capacitor thus simplifying the setup. And now I'm not cycling my expensive HID's everytime I start the truck and go from drive to park.

When you use a turn signal or hazards, do your Headlights flash?

Nope. Parking light circuit is low brightness and not the same as the turn signal circuit.

What is totally stupid is now GM shoves this DRL and Auto headlight stuff at buyers who don't want it (and are forced to pay for it) and make it a PITA to do anything about it. It is not a government requirement (U.S.) and I detest some nanny stuff using the at risk fallacy that someone, somewhere is too stupid to turn their lights on when it is prudent to do so, therefore the OEM has to force everyone to do it 24 hrs a day. I think with well over 5 million miles as a commercial truck driver with no vehicle accidents, I have figured out the best time to run lights and when I don't need them. And I don't like lights coming on at night or low light when dealing with livestock in the field or hunting. I have learned to understand that the OEM's do not build pickups to actually do anything but be cars on steroids and basic transportation on hard roads. Heck, everything that a pickup would actually be used for (and advertised and marketed to do) is considered severe service in the manual. The OEM's figure that the only thing a pickup will be used for is a daily go to work vehicle or grocery getter, and only used to haul a lawn mower to a repair shop. And they think that all their customers are a bunch of rubes who cannot figure out what a headlight switch is for. Of course, there are those folks, but the nanny state "at risk" fallacy permeates the OEM mindset.

It's very easy to turn off the headlights.

 

I like the feature, people don't understand that if you can't see the sun, your lights should be on.

    • I gotta say, I'm enjoying your narration. The troubles you've been having are amusing as you describe them. It's good to see that you're finally getting some satisfaction out the old beast though.
    • Declaring victory would upset the demons that possess this Blazer, so I won't. But I did make progress today--after it put up a fight. Always a fight.   I had the day off so I spent the morning cleaning up the shop and I thought I'd get ahead of things by filling the cooling system in prep for the final part I needed to arrive: the driver's side knock sensor. Glug, glug, glug....and then the unmistakable sound of liquid hitting the shop floor. It induces the same chagrin when the sonar and targeting laser temporarily malfunction during a late night bladder evacuation over the toilet with the bathroom light off. D'OH!!! That made a mess...   Oh, hey, that knock sensor I removed? It threads into a wet port. Who knew?! Learn something new every day. Put a pin in that chore, I'll fill it the rest of the way later.   The knock sensor arrived at about 1pm. I threaded it in, connected the wire, filled up the coolant, checked for leaks, and... drumroll.... fingers crossed for a perfect start, excellent timing, model fuel trims, and ...no squeaks... Here goes.....   No, it didn't start. At all. I cranked it a few times and it wasn't sounding good. Furthermore, I heard leaking again. Jesus H Tapdancing Christ, stop leaking all over the dang floor. This time I had accidentally overfilled the coolant reservoir and the churn of the water pump via cranking caused a bit to burp out. Ok, just, breathe... Put the flamethrower down. Dang thing wouldn't burn anyway, leaks too much...   Did you know the rotation of a round crank sensor in a round hole, matters? I do now. Took me about half hour to retrace steps and realize what I had done. Then it started right up.   No squeaks. The squeak was the old balancer.   Once it entered closed loop, fuel trims are dead on, hovering right around zero at idle. No more -30%. I'll credit the injector rebuild on that one.   Timing? I think there's an OBD 1.5 translation error with my Actron scanner. It's anywhere from -20 to -30 at idle, sometimes as high as -40 cruising. Sorry, the engine just isn't running that smoothly at -40 degrees ignition advance. It's just not. It's smooth all through the rev range and has decent power. I'm going to have to trust the seat of my pants on this one.   The new exhaust is very quiet. The old catalytic converter? Not melted, but definitely not healthy. Rains glitter when you turn it on its end...all the precious metal is flaking out. Once the new exhaust system burned in/smoked off a bit, the engine's exhaust smell is normal again. Not that I'd recommend going around huffing car exhaust, but, you know what I mean?   One problem to correct. The new exhaust has the opposite problem of the old spliced up exhaust. It wants to hit the floor where the old one wanted to rest on the cross member. Happy medium, please? Still noodling on that one, need to look at how I can adjust some hangers.   I don't know what's next. On one hand I want to run away from this thing as far and as fast as I can -- there have been a lot of NOT fun moments. On the other, now that it kinda drives nice, maybe drive it around for a little bit?   Shhh... it's not currently dripping oil all over the floor. I can see just a little wet at the bottom of the timing cover where it meets the oil pan seal. It's not dripping multiple drops with every ignition cycle, in fact, after some driving this evening it has yet to even form a drop that could drip off yet. But the weekend is young... I fully expect this could turn into Exxon Valdez by Sunday. Because this Blazer hates me. LOL.      
    • About that:   Once upon a time in a land far far away lived a car company that was shy about taking your money and wanted to be sure that they gave you more that you asked for so that you'd come back. No really, not a fairytale. 😱   But after the field got thinned out enough to limit the competition it seemed good enough to give you only what you asked for. Fair enough I say but in such a market you have to give something the others are not or they go to the one who does. Gimmicks or glitz. Oh, fins and chrome. Yea, shinny crow like cars. Yum.    Field narrows a bit more and 'brand loyalty' becomes a thing and the minute it does they start thinking to themselves, "Could we make more money if we gave them less than they expect and they will hang in there for brand and comfort with the known?" They gave it a try and da*n, it worked!!    Well, what if we teach them, groom them into believing that less is "Normal" and cut some more corners. Will that work? Oh heck yea!    🤔 I wonder, can we give then WAY less than they expect and make them mad enough to spit nails and STILL get them to pay up? Sure, if we get everyone else to do the same so that the choice is less or nothing at all. How would be do that? Platform sharing.  What a concept, right?  Steal like there is no tomorrow and it's legal too!    Truth is no one is going to give up driving, not for very long. The Gen Z crowd is fine with it and will be as long as someone not Gen Z will haul them around. At some point we all die.    Economic voting only works if you cast a NO vote now and again and enough of them to get dumb and dumber to wise up. Well, that's how I was taught anyway. And it should have worked. Would have worked. But the Bail out!!   Look, you have another choice if  you take that bag off your head. If the dumb it down to some predetermined expectation of how John Q Public will use it the, that is under design it to failure they you use it to a lower stress mode. D'ho!    A 1950 Royal Enfield Bullet 500 will go anywhere a Suzuki Hayabusa will and for just as long. But you will have to treat it for what it is and not for what you wish it was. 
    • Maybe I was just too unlucky, but I had nothing but bad luck with Bridgestones. Out of 3 sets, they all started losing a lot of air when they got down to about 1/2 tread life, and at that point also wet traction suffered more than it should have. Also, the only tire I ever had in my 60 years of driving that had a side wall blow out was a Bridgestone.   I'm currently running Goodyear Wrangler Workhorse AT and am very happy with them.   
    • maybe when the trip is over, check all the other joints in the front end, like all the ball joints, tie rods, pitman & idler arms, etc...
