Today I went to plug my newly obtained '88 dash harness to my '87 tbird's engine harness and the connectors that connect the two are different. I got the '88 dash harness because I didn't trust the '87 harness after the dash fire and all. Will I need to use the '88 engine/light harness as well? Thats ok if I do, because I got those as well at my local junkyard. Thanks guys!

I can actually help you there. You will have to use the 88 engine harness. And the light harness may plug in and it may not. Depening if your car had systems sentry or not. The connectors are differernt. One is black and one is grey. Black for sytems sentry and grey without. This I'm not sure if 88/87 matters.

Coolness! Thanks claude...You wouldn't mind if I refer to to you by you first name would you? I think I'll just use the '88 light harness as well being that the '88 car had systems sentry. I wish I could go outside and replace the light harness right know, but old man winter deemed it fit to give us more of the white stuff along with some nasty wind:yuck:
