165 fuse box wire help

Postby 88st165 » Fri Aug 05, 2016 2:15 am

Can any 165ers help me out? Trying to identify this wire that is on the body harness side and plugs into the fuse box. I am in the process of pulling my engine to do the st215 swap and noticed this wire was a little burnt and melted. Car acts normal but I don't want any issues down the road so looking to maybe repair it. In the attached image you can see its fusebox location in the background. Image

I recall that wire broke on mine which caused the interior lights, cluster lights, tail lights, and headlights to not work. Have you tested yours?

Yea they all seem to be functioning as normal. I think I have another body harness somewhere I can steal the plug end from and replace it if it's in good condition.

That looks like one of two connections that go to the starter. It is uninsulated and exposed to a great deal of heat which accounts for some of the starting issues 4th gen celicas have. This is, however, from memory and I could be mistaken.

That is the power supply from the alternator to the body fuse box.
