I'm Installing a DEI 545T Nite-Lite Module and I need the Wiper Output wire color and location, So the lights on when Wipers are turned on. Thanks in advance

Without a FSM I can't say off hand..perhaps someone will come through.

If not...try this.Drop the panals under the dash and probe the thinner wires coming down the steering column (don't touch any SRS (yellow or orange covered harnesses) and read with A DMM what the wires do when you turn the wipers on and off..there shouldn't be too many wires coming from that stalk area.

Good Luck

doh..I should have thought of directtech,,I didn't think they would list the wipers but it is a DEI part..but...it can never hurt to learn how to find wires yourself if need be.

Enjoy
