Hello Everyone, I'm helping a friend with his truck, 2004 GMC Sierra 1500 SLE 5.3L. Removed and replaced forgive me if the name is incorrect the I/P Harness that runs from the Fuse Block under the hood ,through the firewall, and runs along the dash. Got it out with a struggle, install went smooth until the reason I'm asking for help. I have a connector that I can not figure out where it belongs??? It's a grey with 8 cavities with 1 Black with White stripe (Ground), 1 Brown, and 2 Brown with White Stripe wires. It exits the harness where the headlight dimming switch connector does. If anyone can help me or if you need more information please let me know. Thank you in advance for your time.
