So, I bought my 89 Supra a couple months back and had a couple questions which I got answered quickly on this forum so I have another one. My 89 has had a 7M swapped in and they had to splice the harness in for the motor, as I know these cars had a couple different harnesses. Now my question is, that the current CAS in th car has three white wires coming off and soldered into one before the pigtail going into the wiring harness and I wanted to know what year CAS has only one white wire? The one in the CAS is acting up and will randomly ground itself to the motor and is beginning to act up.
