TCC does PCM switch ground?

Post by Helical »

I'm in the process of putting a T56 into my VS Series 3 Maloo (auto).

Plan is to use the TCC lock up (pin C1) to operate the reverse lockout solenoid of the T56. Looking at the wiring diagram the PCM switches ground with positive supplied via igntion. Just wanted to check this is right so I don't end up frying my PCM.
