Wiper System Question

OK I figured it out! I’m happy to have the variable wiper system working finally. It's been a challenge getting this working. First variable speed wiper motor I got only worked on one speed. The second motor on the bench test worked but not when I installed it. And like every other electrical snag I’ve had on this car it’s been a GROUND!! The grounding strap on the motor wasn’t tight or cleaned. Then I kept on testing with the dash out and the wiper switch dangling there. It still didn’t work until I touched the switch to the dash frame. OK, from now on I’m checking my grounds first for all other electrical problems. It would have saved me a lot of time and headaches if I did this first; on the up side I learned a lot about the wiring under the dash I’m sure will come in handy later. I haven't tracked down the B1 Violet wire but I finally got the wipers working. I'll check if my reverse lights are working later.
