I have a windshield leak running down driver side A pillar leaking all the way down to the kick panel and the wire clusters inside. Looking to see if anyone knows what the wires are in kick panel and also where the g203 ground wire and splice pack run to. Really looking for as much information as possible. The leak has been there for a few years. Thanks

 

Can't do much for you without any vehicle info.

Take a look. the panels usually just snap in , or maybe have a screw or two holding them in.

The drivers side is typically where the engine harness comes through the firewall and joins the rest of the system. Additionally, there are usually connections to the door and instrument panel harnesses, and fuse box/convenience centre.

you might find schematics on gmupfitter.com or charm.li

that's too bad. Should have been addressed right away.

 

Sorry. It's a 1999 Sierra 1500 4.8 2wd

 

looking to find out what both of these plugs are
