man those things are bright! where the hell where you about 6 months ago when i was doing this! good write up man

 

Hell ya! Cool write up. I might add a second set like that. :drink

 

I have two questions.
1. Is the wiring the same for all model years?
2. Did you just use a regular single switch?
Thank you

 

unsure on model years. Check to see if you have the green wire in the same location of the BCM, If so, check it with a test light to see if there is power to it when the truck is in reverse. I believe the reverse lights will come on if you have the ignition in the on position and the gear selector in reverse.
If no lime green wire, check around with the test light, it may be a different color on different model years.
Mine is 2006

I used a lighted switch that came with my aux. lights.
Its basically a grounded single switch that lights up when its in the "ON" position. I went this route so i don't accidently leave them on when rolling down the highway.

 

and you said you don't have time to install the 4094.

 

yeah yeah yeah.

callin around for an lb7 up pipe, picking a egr delete tube, and gonna get the washers/nut to shim the fuel rail valve. I like to do as much as i can while i'm in there.
It'll be on soon!
We'll see who can get their stock tranny to last longer drinkin:

 

Anyone done this to an 02 model yet I can't find which wire under the dash goes to to reverse lights????

 

Cool mod. Gotta find a cool set of lights and a way to mount them so they look oem first.

 

thanks, i use them all the time when i unload stuff at night. turn these on and the cargo light and i can see everything on the truck and trailer.

 

You can use a relay, and pick up the green wire at the rear crossmember, and the power from the trailer plug -- then you will not have to string wire from the front. The lights will go on anytine the vehicle is in reverse and key on.

GM has used the lime green color wire for back-up lights since the early 50s.

 

Great timing that I found this thread. Got my switch in, b/u lights come on. Getting ready to wire aux light. It is a single 55w halogen 'flood' light, 3"x5" tractor work light type. Will the lime wire at the back of the truck carry enough power for the b/u and this light? I've had it wired into the trailer b/u circuit at the 7 way plug, of course that only comes on in reverse.

What amp fuse do I need in my switch? Thanks.

 

Welcome to the forum! :drink

Weres the lime wire at?

 

Thanks. Best I can tell, the OEM b/u lights should pull 5 amps and my one aux light will pull 5 more. Think b/u light circuit was a 20 amp fuse under the hood.

I'm guessing the lime wire under the dash is only a signal wire as it was not very big, 20g maybe? Lime wire at the module at back of truck is bigger, probably on the 20 amp fuse. Got a 5 amp in the switch for now.

 

Very nice work, that certainly takes the effort out of running a long wire.

 

This is a good idea man. Another option that you can do instead of having a seperate switch, is to use the bed light switch. That way when you hit that switch, the lights in the bed and the extra lights all come on with just one switch instead of 2.

 

Sexy! i like it

 

if you go that route however any time you throw the truck in reverse your bed lights will come on, which can be potentially blinding at times.. just my 0.02

 

Stick a diode in there - problem solved

 

Thanks! I have a aux set of b/u lights but will add this to it. Great write up!

 

Thanks guys for all your posts on back-up lights..I was able to install a Hopkins back-up camera on my 03 Silverado today thanks to knowing the lime green wire secret in the trailer harness...much easier than going into the tail light assembly.

 

thats sweet man

 

Thanks TDI Powered!
I ran the black ground from the camera/monitor harness to the frame (with a little dielectric grease), but for future reference, would I be correct to assume that the darker green wire in the trailer plug harness is also a ground, and would be a more weather resistant connection with a Scotch lok and heat shrink?

 

Sweet

 

great timing

i just found this thread and am about to install some myself. i was wanting to be able to wire it up with the reverse lights but wasnt 100% sure how to do it. thanks for the write up!

 

i have the same bumper were did u get the lights?

 

walmart or advance auto.
just some cheapies.

 

Ok, I am resurecting this thread with a question (or two). Does anyone know of this circuit comes through a relay, and if so where is the relay? I plan on adding a couple of lights on my truck and on the trailer as well as a BU camera that I want to switch off and on. I need to determine if I should install a relay on the load side instead if running through a switch.

 

The contacts of the relay will be the load side and the lime green wire, or the switch will power the relay coil.

 

Looks like they light up nice!
