You will want to try the "parts wanted" section.

I don't see where anyone clarified what wires they hooked up to power, ground and the third wire? I just bought a set and the wires are numbered but that is all.

Well I am on my way to answering the question myself, I found the wire chart posted and it states the following for each number:

27
INSTRUMENTS FEED (INSTRUMENTS WITH POLARITY)

57
INSTRUMENT PANEL GROUND

71
WINDSHIELD WIPER CIRCUIT


57 is obvious but I am not sure if 71 is the constant and 57 is the switched since it refers to the instrument panel?

 

[deucer]

It appears (unless someone corrects me) that 27 is switched power so the wipers will only run if the accessories are powered and 71 sends power to a windshield washer when the wipers are running and the button is pushed.

I have the a3 wipers in my a2. 71 is the washer. Or in my case a dangling wire since I do not have a washer installed.

Thanks for the help. I was wondering what fuse or breaker rating is everyone using when wiring in a truck that did not already have wipers? I am wiring into one of the pulsetech units and I presume the 7.5 would be enough but maybe a 10?

Good info guys. I plan on installing this upgrade real soon. Thanks for the pics! I'm a " visual learner"

As this was a government up grade (I believe the part # 57K3240) Does anybody know how they did it. Also anybody know where one could get the whole kit and kaboodly as it was a upgrade? I don't like missing parts or half butt repairs unless it's just to get you home in a pinch
