  1. GM Electrical Tech
    Hi! I was able to replace the oil pressure sensor, but the connector was so brittle and I ended up with a broken connector. Now I bought a connector but the wire colors are black red and yellow while the original are black, tan and white. Please help which wires should be connected. Thank you!

    My heated steering wheel is not always working in my 2013 LTZ burb. Every now and then when I press the button, the LED Illuminator will flash quickly but not stay on.

    I have a 1997 k1500 z71. I recently bought a 1991 k 1500 parts truck. My question is since the 91 has the older style switches and wiring harness. Can I find anything in the aftermarket to plug straight in to my existing truck harness to convert it to the older door harness. My problem is that I...

    Hi all, I’m currently installing a CB radio in my 1994 C1500, and I need to wire the coax antenna cables through the firewall. Are there any preexisting holes or grommets that I could piggyback off of, or would I need to drill a hole? I want to do as little collateral damage as possible...
