Looking for someone to help me make a torque converter lock/auto/unlock switch. I've got an on-off-on switch with three posts. How do I do this and which wire is it in the trans wiring harness. Thanks in advance.
Lock up I know how to do, I want to wire it for unlock on the switch also and I'm not sure how to wire the switch to do this. I know where to find the wire, just not sure how to wire it.
Look at lower switch in image.
So simple.
Center is the wire out to the trans. Top is the other side of the wire from pcm, bottom is ground.
Switch up = locked
Center = unlocked
Down = factory
Have fun with the flashing OD light when using the switch anywhere other than factory.
Doing it the correct way with a relay is out of your league.
