Reconnecting Center Brake Light after removing sports bar
McCoys posted a question in Ask the GM Technician
I bought a 2021 Silverado 1500 Trail Boss that had a dealer installed Sports Bar that had a center brake light integrated in the accessory. I removed the sports bar. I found instructions that I followed perfectly up until the part that re-connects the brake light wiring in the Delphi Connector under the passenger floor board area. Remember, the instructions I am using are for the installation of the sports bar - I am reversing the process. The instructions identify pin #39 to be the pin used for the center brake light on the truck. however, there is a wire already using pin #39. Remember, I'm reversing the installation so that #39 should be empty if the installation called for this pin to be used as the original factory integrated center brake light. The instructions do not identify a wire by color but the wire that is currently not connected is purple. (see pictures) I am only assuming this was the original wire that was connected to one of the pins (not #39) but I have no idea where it should now go. (if in fact it is the correct wire for the brake light) these are the instructions that I followed successfully up until #13 on about page 12/13 (the pages are not numbered). https://uploads.tapatalk-cdn.com/files-27/1597173956_84571746.pdf any help is greatly appreciated.

I have an 04 gmc Sierra Wt with a weird issue. it started when my battery went bad. i use the intermittent pin in the body-12 way-brown in the cab fuse block as an ignition driven accessory. the first thing i noticed was the accessory would only work every now and then. next the blower stopped working, the abs and brake likes came on, all at the same time. after messing with it all day here is the current issue. the abs and brake like come on when the blower speed control it set to any speed other then 0. when set back to 0 the abs and brake lights will turn off. the intermittent pin on the body-12 way-brown has low voltage and cant power my accessory. the constant power pin next to the intermittent pin has full 12 volts. I have checked every fuse and cleaned the ground on the forward driver side and the ground in front of the driver side suspension. I have also added 3 ground wires cab to battery frame to battery block to battery I am at a lose for what to do. Could it be a bad relay? -
Hi, I have a 2005 Sierra Denali. When I got the truck from my uncle who was the original owner, the gauge cluster, which was brand new installed by GM did not illuminate the ABS and BRAKE lights. Everything else works. I pulled the cluster apart and tested that those LED’s work, and they do. I replaced the ABS pump unit because it was not functioning, and had the EBCM rebuilt. The ABS functions correctly now with the exception of those lights that have never been on since I got the truck. Even if I press the Parking brake/E-brake, the red BRAKE light stays off but it will ding at me if try to drive with it on, similarly, before I replaced the ABS pump, I got a message in the odometer screen saying “Service Brake System”, no lights from either. No fault codes. They don’t even come on when cycling the key, but all the other ones do. I’m at a loss. Can’t find any broken wires or bad grounds. Any help would be great. Thank you!
