lock up help
Ok i know this has been beaten to death on here and i did search but i still need some help.
i went to carb on my car and tossed the computer and harnesses and now i need the trans to lock up, so from what i gathered on here is i ran the purple wire from the trans connector to a 12 volt switch power and the tan/black to a switch and then added another wire from the switch to a ground.
i took the car out and flipped the switch when i was cruiseing in fourth and felt nothing. i played with the switch flipping it on and off driving stopping everything and felt nada. i read on here that the car would bogg down or the rpms would drop some if it was working.
also this is the 2nd trans i put in and i tried it with the first trans and nada same with the 2nd trans nada
do i have this think hooked up right?
i plan on getting the painless lock up kit but i was looking for something to work for now.
thanks

If the lockup is functioning you will see a few hundred RPM decrease at cruise and it will stall the motor if you stop with it locked.
The original harness in my car had a single green wire...
