I changed my 88 Notchback to MAF. If you use a 1989 computer( A9L )and the main wiring harness from the computer(from the 89) to the motor, it is a bolt in deal. All the wires fall right in place. No cutting,splicing,nothing. Hardest part of the whole job is getting the firewall grommet back in the firewall once you install the new harness. Let me know if you have any further questions.
