1987 Pontiac Firebird 6 cyl Two Wheel Drive Automatic

hi. I have an 87 firebird and it used to have a v8 in it but I am trying to put a v6 in. But I have no idea if I need a new computer and wiring harness or what all I need for the swap.

The wiring is the same but you will need a computer for a 6 cyl. Most times they can tell you the interchange at a local junk yard and one can be picked up at a local junk yard.
