Can a TBI 700R4 work in say a 1985 truck and the lock up torque converter still function? I know that the TV cable is different, I can switch that. I'm wondering about the electrical plug for the lockup solenoid. Can we plug that in with the '85s vacuum switch and it still function correctly? From what I understand, TBI uses the computer to control the lockup, I've never owned a TBI/700R4 truck so I just need to know this. Tranny is from an '89 K5 with TBI obviously. Anyone know?
