I have a painless harness and i need to wire up the wiper switch. I do not have a plug, there are three wires and the switch has the terminals in a L shape on the back of it. Two wire go over top of each other and the third is offset to the drivers fender. Could someone tell me which one in offset and which two are over top of each other for example LB over black and DB offset to drivers fender. Any help would be appreciated thanks as I really dont want to pull this switch out of the dash it looks to be a real pain to do.
