Fixed your title as best possible, being legible will greatly increase your chances of getting help.
Same for your post, it's very difficult to read due to slang, text-ese and mis-spelling so be aware many may pass this by.

Yes, as long as the harness and the car receiving it are both OBD1

Just be sure the harness is pre 93, or else you will need to swap inj connectors.
