Okay so my 91 jeep cherokee has never had a rear wiper setup. So far i have collected: A wiper motor, and the wiper/sprayer switch. The line for the sprayer is already run to the hatch. What else do i need to get, and how do i go about hooking the switch up?

 

To a limited extent, this depends on your year. The obvious are required, such as the wiper arm, and bushing/ spacer/rubber thing. If its a post-90' it should have came with the relay (or at least it is an attached set-up), however if it is a pre-90' it is a separate relay just beside the motor.. Also if your Jeep doesn't have the switch on the dash for the wiper, that may be necessary.. And it should already be wired for all of this, so as to make your life significantly easier.. Just something to getcha started.

 

also need proper year washer bottle with dual motors if you want that to work also

 

Got any pictures of that by chance? Havent seen one with 2 pumps in the junkyard
