I have the intermittant wiper harness ready to install and want to test the signal wire first. I untaped the brown wire/blk stripe that was folded back on the loom going toward the wiper motor. Should I get 12 v signal in that wire with the ignition on, and wiper switch in the full-down position ( i removed the tap) ?
I stuck a grounded test light into the connector with the switch on and got NADA Perhaps someone who has does this retro-fit can halp.The wiper switch is either a late model VW or 924. It runs the washer pump in the pull-bak position Thanks, Jim |

I believe the wipers have to turn on first for it to work.

I guess I'm wondering if the brown wire/blk stripe is a ground ? Looking for someone who has done this install and did some trouble shooting Jim |
