I got a 89 Mustang LX with T5 and good running motor for $200 YEAH ME!!! I want to know if I can use the harness and switch a few pins for the LA3. I screwed up all my harness' trying to change them back after mucking them all up. I have a perfect mustang harness and I read somewhere that a person can switch pins and go go go! Anyone have a diagram or know what ones to switch?
