what wire do i use to connect a trans temp to my auto cav.

You need to install a sender... there isn't one on the car in stock form.

If you've got a 4 speed... on the front of the case, where the cooler lines are... there's a spot for the pressure test... you screw the temp sensor in that hole.... try to do it quick so you don't lose a bunch of fluid tho

I used the Autometer trans temp gauge... threaded right in...

yeha ive got a lunar one that i took off my friends old z..

john ill let you hump any day!!!
