Hello everyone I'm new to ranger forum and have some questions. I'm trying to swap a 1986 turbo coupe motor into my 1991 ranger. I have the complete motor and wiring harness with computer from the donor t bird. My question is can I use the existing wiring harness in the ranger and just change the computer? Any good advice would sure help Thank you.

 

Was the '91 a 2.3l?

Yes it has a 2.3 in it right now so it should fit good with not much problem
