There are three wires going to my lock-up. A pink wire that has power all the time, a tan/black which has power when the plug is in, and a blue one that has no power. Which wire or wires do I need to ground to get lock-up to work?

to make it lock up u can run a wire with a switch on the aldl thingy.
there is an article in the "technikal archives" section in this webstie.
I just did it today to my car and it is great.

I figured it out for myself. The wire that gets power from the tranny (tan w/ black strip) is the one that should be grounded from a switch. I had it hooked up but I couldn't notice it on the lift. I had to drive it on the highway to see.
