Need help with wiper/washer wiring
Hey guys....it's that darn Chevelle guy here again.....but this is a legit Camaro question!
See the pictures below:
I'm working on an intermittent windshield wiper project. I was able to obtain an '81 ??? Camaro "pulse" wiper switch--the one where you rotate the knob when it is the delay position and depending how far you rotate it, you set the delay between wipes.
Can anyone help me figure out what the rear lugs correspond to? Wire color wise/function wise?
There are 4 lugs and one green pigtail. I know the green pigtail is the delay signal wire that goes directly to the pulse circuit board inside the washer pump housing.
I believe one lug is the main ground connection for the switch. One lug should be signal to activate the washer pump and the last two lugs would be the signals for HI and LO speed.
Any help appreciated.
