does anyone have access to the part numbers that would actually comprise the plug-n-play kit? there may be some alternate sources outside of the dealer...

I got all my Delphi connectors to make my own plug and play harness from the place you suggested for the ABL connectors, www.Mouser.com. They have a wide selection of parts, good prices and fast service. I'm like a kid in a candy store when I go to that sight.

yeah, that's what i had in mind. If someone had the connector p/n's I was going to look up all of the required parts. (connector bodies, TPA's seals, etc etc) and post em back up here

how do i know if it goes back to the PCM?

oh man... this is tough to explain in words...

hold on... i have a great visual...

IROCanSS · 02-08-2010, 10:38 PM

The red arrows are the flow of current. In the first pic the car is running during the day and the DRLs are on. Not the power flows through the one diode (blue arrow) to the light from the PCM but can not flow to the switch b/c it is blocked by the diode.

In pic 2, the lights are on, either its dark or you flipped the switch. the power flows to the park lamps and through the switch, through the doide and to the DRL wire. The other diode blocks it from going back to the PCM. If this diode was not in place, it would flow back... BAD.

This help? Look a few posts up and you can see my other diagrams without the red arrows.

Can you use the non-RS light switch (the one that has the foglight switch built in) in an RS car and use it to control the DRLs as foglights? For instance, if I bought the headlight switch for a non-RS Camaro from my local Chevy dealership and swaped it into my RS equipped Camaro. Could I use that factory switch to control my DRLs as foglights if I wired the lights up like in your diagram?

Yes... BUT it takes a lot of work. A local shop did eventually get it to work. A guy brought one of his SS (he has 4) Camaros to be the guinea pig. To get it to work, the shop tech had to open the switch and do some rewiring of the circuit board in the switch and had to oopen up the PCM and do some rewiring in there. Now this guy has more money than what ever holy spirit you believe in so he didnt care if the car fries. i am not in this boat. I ran a second switch but I am considering cutting the DRL lines to eliminate any chance of backfeed. I NEVER use my DRLs. It is the first thing I switch off so just cutting the feed to them is not a big deal to me.

If you find another way, please, let us know but this is all we have found out so far.

ok guys, try to follow me here...what I am looking to do is this:

#1 - switch the DRL's into foglights that come on when the parking and/or head lights are on.

#2 - make it so my Halo rings are my DRL's during day and still have normal opperation at night or when the switch is on.

Basicly what i'm going for is to have just the Halo's during the day so that no other exterior/interior lights have to be on .... AND .... I want to be able to just have Halo's with foglights as an option. I want to be able to cruise town with just Halo's and foglights when I want to. The headlights take away from the Halo's when they are on and you can hardly see them, but if you had just Halo's and foglights then the Halo's would get more attention and foglights would provide adequate lighting on streets in town.

I have a very limited knowledge of electrical wiring but was considering the following:

#1 - Disconnecting DRL's wires and splicing them into the Halo lights power wire. This would give the Halo's power with lights off and DRL's on. Would also turn off the DRL's.

#2 - Then, splice into the Halo's main power wire and run that into the DRL's connection that was previously disconnected in step #1. This would make the DRL's (which are now foglights) come on any time the Halo's get power from the switch.

Is there any chance you could fry something by splicing these wires together like this?

The last thing I wanna do is burn my car down...LOL.

I feel that splicing off the Halo's to make DRL's work anytime the Halo's are on is no big deal because I'm just adding more lights to the circuit...

but I am concerned about two different power sources coming together to power one light at different times...could either source "push" current up the non-powered wire and cause issues ? I would think this could cause a feedback issue.

If anyone has any suggestions on how I could do this, it would be greatly appreciated, and I dont mind spending a few extra dollars to be safe ( i.e. installing a relay vs. a diode)

Thanks in advance guys...hope the post wasnt too long and bored yall to death before finishing...haha

Take care, and thanks again!

Channing

IROCanSS · 02-11-2010, 10:06 AM

seems to me you are just swapping the roles of the DRLs and the halos BUT you also need to send power to the halos for night time operation...

Let me think about this... I will get back to you.

Anyone else feel free to chime in. I think as long as you dont back feed the PCM you should have no worries...

My suggestion is this.

strauchpete · 02-11-2010, 04:07 PM

djc ya if I am getting you right you would really just need to put the DRL on a switch in the car and then move the DRL wire up to the halo wire. So then they halo will work just like your DRLs do and then you will have full control over the now fog lights.

SS Drifter · 02-12-2010, 02:15 AM

Keep in mind that using a diodes will result in a voltage drop so the lights may not run as bright. Also using a diode as a wire interconnection may result in mechanical failure of the diode at some point. Kudos to "thebrainhart" for his pioneering idea but the extra effort of using a relay is probably worth it in the long run.

While installing my 9500ci I ran an extra wire up front just for the purpose of DRL lamp control. (I'd rather see a relay close to the lights than running the light circuit back to the instrument panel.) A DPDT relay would completely isolate the DRL lamps from other circuits, without voltage drop.

wadew2lt · 02-26-2012, 09:27 PM

The typical voltage drop accross a diode is just over half a volt at only 0.6V.

Hey Toasty, have you had any progress on this yet?
