Wiring GMC Acadia

Can anyone tell me if there is enough room in the tail light housings for additional bulb sockets, or do I need to use diodes?

My 2008 was done with an additional socket for an led-type light. Sits on top of the oem bulb installation. Has worked fine for 3 years.

Thanks Bob. So where did you get the additional socket? And I presume you drilled an additional hole in the housing?

[BCook57]

The installer, at an RV service center in Punta Gorda, Florida, did all the work. He suggested the fixture and make it all work together. Sorry I can't offer any more details.

I do know that it eliminated the need for the diodes that came with the Blue Ox wiring set-up.

I'm woefully ignorant of anything technical.

Thanks anyway, I am sure he drilled another hole in the back of the light housing and installed another light socket.

I used diodes on mine, but it looks like it could handle another bulb if you want.

I ended up using diodes. When I took the tail light housing out there appeared to be plenty of room, but when I looked real close there did not seem to be much extra room inside. I sure did not want to put a hole in the tail light housing in the wrong place and ruin it. I bet they are real pricy.

Good choice. I've been running the diodes for 3+ years and 25k miles of towing and they do fine.

I had an 07 HHR wired with diodes. A GM master Tech found all the wiring under the hood to do the install and nothing had to be wired in back under the carpet. Works great and maybe I was lucky to find the right guy to do the job.
