Are you using the same grounding point on the rear passenger frame rail?

85 is not PnP w/ fast back.
You will need to rewire car to make fast back lights work.

yeaa i used the ground today and only some of the lights seemed to have turned on i dont think i got a reverse light , but the car battery died , if theres shorts how could i possibly find them and is ther any threds that show the rewire for the fastback and thanks for your help

Yes, I did the conversion on my 88 and there were some threads that explained moving some pins around in the big connector to match what your 85 needs. Try searching and reading all the conversion threads until you find what I'm talking about.
