I am new to this site and could use some help on a build I started. I have a 1988 convertible 2.3 auto very low miles and very clean. Only problem is a bad engine. I have a 1991 2.3 8 plus engine and I need to know what wiring issues I will have. I have the harness and computer are there any wires that need to be repined or will this be a just an ecm swap thanks for the help in advance
