Hi. Have a question about my 1989 gt. I have owned this car since i was a teenager and trying to correct some of my mistakes. I found a wire that appears to be a ground for the main harness by PCM. Does this look stock from the factory to any of you? Appears as if someone spliced a wire in.

I should clarify, I am not the original owner, but I have owned this car since 1996.

Hey Karthief, love your posts around here! Anyway, sorry forgot to mention, right by where the pcm is, passenger kick panel. I wouldnt have even noticed this but i swapped an a9p recently, and this looked strange to me.

Glad to hear I'm earning my keep. If the janitor sees this I may get a raise I've have not dug into much wiring in that area but the radio antenna wire comes to mind, don't know why

Antenna? Yeah, your guess is a good as mine. For the time being i put a wire loom on it, seemed a little weird being exposed like that but its a ground for something, so maybe doesnt matter
Thanks!

Looks like the antenna wire. You cam see it through the gap between the door and fender. If you pull on it gently you should see it move.

That open spliced wire is normal and suppose to be like that.
