1989 305 TBI Auto to 305 TPI 5 Speed
I have a 1989 Trans Am 305 TBI with a 700R trans. I just bought a 1989 Formula with a 305 TPI, 5 speed trans and 3.73 posi. I know all the electrical under the hood has to be swapped. My question is: Do I need to swap the electrical under the dash since they are both the same year? Also do I need to change the fuel pump?
Thanks in advance
Thanks in advance

Just an update for anyone who asks the same question, yes need to swap fuel pumps and yes need the wire harness under the dash.
