Taillight wiring issue

[pearl91chevy]

Hey guys I'm fighting a brake light issue. I was wondering is there only 1 ground wire on the harness to frame for the rear lights? Should be in the C section of the frame correct? All my front signals and light work correctly but the back does not. I also replaced the bulbs last night since most were popped.

Sorry I was not specific, I tend to forget which I'm working on. This is for my syclone. Thanks for the info Dave, I'll check it out tonight and report back. I did clean the ground on the frame but didn't change anything, I hit the brake lights and the reverse lights come on, only my left signal works for tails, and the courtesy light for the pass rear is very very dim. I'll check the grounds over again tonight.
Thanks again Dave

Re: Taillight wiring issue

First thing I did today was check the ground on core support and made sure it was a fresh ground. I also replaced the rest of the builds, backup, front bulbs and license plate lights. It ended up being the ground on the rear harness to frame. The wire broke inside the insulator before the ring termal, I replaced the wire and all is working.. Besides the license plate bulbs. But signals work correctly now atleast.
