As most of you probably know, TJs without factory hardtops do not come with the hardtop wiring or switches.
My TJ is one of them, but I got it with a hardtop and it seemed simple enough to add a few functions. I put in a double pole momentary switch. Pushing up operates the wiper one time and returns to the parked position. Pushing down operates the rear washer pump. I used 14 gauge wire wrapped in protective wire wrap that follows the original harness under the dash(over the steering column), back and below the drivers side door under the trim, and finally along the drivers side of the body along with the factory harness to the drivers side rear where the plug is located.
I didn't want to drill into the wiper washer reservoir, I was afraid my original might crack or leak. Nor did I want to run hose from the front to the back and add a bunch of wires thru the firewall. I found a washer pump tank combo online that fits the space by the plug/ rear hatch nicely and doesn't really take any space that im using anyway and is easy and clean to fill. Plus it can come out easily with the removal of the hardtop which I like.
It was getting cold and dark and I didnt have a chance to take many pictures. But I thought id put together a little sketch and a few photos of the aftermath. I'm hoping it may help someone else trying to do the same thing. Its pretty straightforward anyway, there are really only 4 wires to run, a fuse, a switch, and a pump.
The double pole momentary switch is in the middle and fits nicely in the factory blank. You might also notice my "custom" change holder. I was missing the ashtray and it was really bugging me.lol
I'm sure I could come up with a fancier method to secure the washer reservoir but it fits pretty snug, the tie is really only a backup, it is a Jeep after all. If it's not bolted or tied down, it's going to move.
