Brek,
Since you have acces to P/Ns, and better tech advice than I have - and not meaning to hijack the thread -

1987 YJ, from the multi function switch to a "black box" to the wiper motor - what is the P/N of that box, what is the wiring schematic for the wires - should I chouse to delete it and build something different?
Like I said, mine wipes about 2 times a minute when switch in the intermittant mode - no matter where the dial is set, and will go slow speed, but not hi speed.

It's 1PM on Sunday in Yokosuka
