Quad tail lights for 05 GMC Envoy

[Gerbil21]

OK so as the title says how can I go about having quad brake lights with regular bulbs

I found this thread that talks about doing exactly that but he used led's
http://forums.trailvoy.com/showthread.php?t=63013#/forumsite/20572/topics/63013

He says how to do it with stock lights but isn't 100% clear

The only schematic I found was this:

Can some help me figure out this since not even the schematic shows how they are wired

i've seen that thread he made and it was good but its for a trailblazer the envoys actually already come with the pins but are not used all i need to do is make a jumper wire but idk to where and to which post on the socket the first thread from the os is a how to for it but he wasn't fully clear since he was doing led's

also since the halogen bulbs dont care about polarity can i just wire the socket for led but still use halogen?

Go get the service manuals from Mooseman's thread, grab the wiring diagram PDF, and check out the tail light wiring configuration. That will tell you which color wire in the harness does what, and their alignment with the taillight will tell you what pin needs to be modded.

Yea I just downloaded it on my phone the 02-05 didn't work but I'm looking at the 06 service manual now

OK well I found it, as far as I see I have to jump the Lt. Blue wire to the middle bulb and then the brake wire will give power to both bulbs.

If anyone else is looking for it I found it on page 62 of the wiring PDF in the 06 manuals also since im doing the quad headlights the schematics are on page 57 just in case any one else needs them.

Also I realized i had a slow moment[emoji53] , when re reading the thread on the os that he shows both LED's and the halogens on with quad so I could just do it exactly as he said and it would work with the stock lights just fine.
