RobertISaar Posted May 15, 2012 Report Share Posted May 15, 2012 factory wires for the individual headlamps in a 92 lumi are 16, just FYI, but it should live with 18. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted May 15, 2012 Report Share Posted May 15, 2012 http://www.powerstream.com/Wire_Size.htm for extra assurance. 18 gauge can safely carry ~16 amps. since you're only powering the low beams with the relay, that's 55 watts X 2 divided by 12.8 volts = ~8.6 amps. obviously, you'll see more than 12.8 volts often, but even then, still plenty of headroom.

2k2cse Posted May 15, 2012 Report Share Posted May 15, 2012 I've been running quad high beams for months and haven't melted any wires. I used 18ga for all of them. The only problem I had was my relay corroding and shorting, but that was my fault for the location. Quote Link to comment Share on other sites More sharing options...
carkhz316 Posted May 15, 2012 Report Share Posted May 15, 2012 If you need a diagram for a Monte with DRL's, I have the 4-hi done in mine, that works with the DRLs and keeps their functionality. I'm working on adding a capacitor to smooth the flicker that is present when switching from low to all 4 (high beam) on. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted May 15, 2012 Report Share Posted May 15, 2012 Sure it's flicker and not the breaker? Quote Link to comment Share on other sites More sharing options...
carkhz316 Posted May 15, 2012 Report Share Posted May 15, 2012 No, it's not a breaker issue. I should clarify that I have HID's in the lows and since I have those wired to a relay for power, instead of relying on stock wiring (I was having the typical HID issues initially drawing off of the car's harness), that there is a split second when the dimmer switch is re-routing the power, that the HID B+ relay loses power until the "4-hi" relay re-supplies power the low-beam/ HID circuit. It's brief, but enough of a delay to cause a brief, single flash, flicker effect. It's an oversight on my part, but isn't really a big deal as I'm the only one who notices it. I'll essentially be adding a smoothing cap to the relay's coil circuit. Also, the only additional part needed for the Monte's with DRL's is a low-amp diode. I'll try to dig up my 'ol diagram.

MonteCarloDude Posted May 15, 2012 Report Share Posted May 15, 2012 I'm not really sure how it would work since you have DRLs... I was thinking the same. It was wishful thinking more then anything. Lol! Quote Link to comment Share on other sites More sharing options...

I'll essentially be adding a smoothing cap to the relay's coil circuit. actually, this makes perfect sense and has been something i've been thinking about for a while. another option other than an actual relay would be to wire up a high current transistor, that way supplying power will be instantaneous, which is likely the route i'll take.

Jssuper Posted May 16, 2012 Author Report Share Posted May 16, 2012 Hmm only took you guys 2 years to do this... Welcome aboard. Its probably my single most favorite mod to do to GM vehicles of all types. Btw, I wanted to ask Robert. You seemed to be tripping on the "Factory breaker" and the way I wired mine looks a lot like your diagram.... While I have had no issues at all in the 2 years, I would like to see the difference in wiring you are referring too to in regards to the breaker. Using your diagram as an example, could you quickly draw one showing me the difference? Visuals help and I would really like to see what you were after back in 2010.. Thanks.

Jssuper Posted May 16, 2012 Author Report Share Posted May 16, 2012 NVM, I see what you were on about here and Forgive my fuzzy train of thought this morning I am not a morning person . Could you dig up a diagram for the newer cars and apply the magic touch to remove the factory breaker...? BTW, since this mod was done I have also disabled my "automatic light" feature, but opted to keep the DRL. I hated the Buick's automatic lighting because it would turn the lights on at weird times. Now I get to turn on the lights when I want.. not when the car decides to. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted May 16, 2012 Report Share Posted May 16, 2012 got a specific year/model in mind? Quote Link to comment Share on other sites More sharing options...

I had the same problem with my auto lights, so I done the same. I disabled my drls, but hooked them back up because I actually like them better on.

Travelling on some stormy nights it was better for me to turn the headlights off causing the bright amber DRL's to illuminate, made for better visibility that way actually.

Jssuper Posted May 17, 2012 Author Report Share Posted May 17, 2012 got a specific year/model in mind? heck any quad light w-body 2000+ should suffice. I would bet money the wiring is the same. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted May 17, 2012 Report Share Posted May 17, 2012 guess i'll grab an 03 century diagram then. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted May 17, 2012 Report Share Posted May 17, 2012 interesting: 03 century doesn't use any headlight breakers? just a pair of fuses(one for each side), each rated for 15 amps. Quote Link to comment Share on other sites More sharing options...

I gotta check my Haynes manual again, but IIRC you are correct. That is less worrisome than the single breaker.. I wish the cooling fans were programmed a little better though.

iroc2 Posted May 24, 2012 Report Share Posted May 24, 2012 the miniquads--> fogs only work with low beam high beam has both low and high illuminated and the fogs are off Quote Link to comment Share on other sites More sharing options...
Hamp86 Posted April 2 Report Share Posted April 2 Much simpler way to do this is to pull the headlight dimmer relay and jump a wire from pin 30 to pin 87a and then plug it back in. Boom dual hi and low beams. You're welcome Quote Link to comment Share on other sites More sharing options...
rich_e777 Posted April 2 Report Share Posted April 2 Oh man thanks for reminding me I wanted to do something like this years ago. I approve of the the thread bump. Quote Link to comment Share on other sites More sharing options...
