Jimmy, just follow the instructions in the TRL and those that come with the electric wiper kit. Make sure that you do NOT tighten the wiper knob against the instrument panel. Bring it out slightly so that it can move in and out, as it is supposed to. In the past, some have made it snug against the panel and then wondered why it would not work right... As for wiring in a relay, there is no need for that, as I recall. I do not think the instructions call for that, but someone can correct me if I have this wrong. Once you go electric wipers, you will never go back!
