What is the colour coding for the early ('79/'80) 4-wire wiper motors?
There is:
Red (I'd assume power but constant or switched?)
Black (I'd assume ground, but should this ground through a switch)
White
Blue with a red trace
The wiper motor is bolted to the firewall, with an external ground wire from the aluminium housing of the wiper motor, to the mounting bolt on the firewall.... all this looks factory
Are these a 2 speed motor, with no intermittent?
This is for a racing car, and I'm starting with no loom, just a wiper motor. I'd like to be able to switch the wipers on via a toggle switch. I'm a assuming an on/on switch... with one "on" being the wipers going (any speed, don't care whether its fast or slow), while the other "on" would be used to "park" the wipers.
I've tried just powering it up to 12V (though a 10A fuse), to the red wire, then grounding the other 3, one at a time, but I can't get it to do anything.
I have looked at a few different wiring diagrams in a Haines manual that I have, but the colour codings listed in the manual is different to what's coming out of the wiper motor.
I'm not much into electrics (I hate it with a passion actually), so any help would be greatly appreciated
