For my 66 Lemans I have a napa wiper motor with 2 terminals and my wiper switch has three terminals. My problem is I don't know which terminals are for what on either the motor or the switch. I am using a new painless wiring kit and on the fuse box there is a wiper switch B+ wire but I don't know which terminal on the switch it goes to and from there witch terminal on the switch to which terminal on the motor, and which terminals are ground etc. Can anybody help with this? Thank you thank you.
