Hey all,

I installed a L/U trans in my 90 Spirit, which originally didn't have one. Would someone please tell me which solenoid wire gets 12 volts? The thicker blue one, or the smaller orange one? I'm having a hard time finding the correct schematic in my service manual...

My intentions are to control this solenoid with a toggle switch mounted in the dash...unless someone else has an interesting alternative.

Thanks!

Paul

I got some help from others on this idea. A gm pressure switch to shut off lockup when you hit boost, and another switch to shut off when the brake is applied. They only kick in for second and third. There is an adjustable pressure switch that I haven't nailed down yet that would allow light boost to be ok.
I think the mieage would be fantastic from other threads I have read. If you cruise in high vac, the mileage really increases. especially on a free flowing well tuned engine.
