I purchased an OEM hardtop for my 07 wrangler unlimited. Is the factory wiring available?
Has anybody wired a switch for the rear wiper?

 

You can get a kit from the dealership to add on the wiper and defroster.

 

I installed it on mine. The only problem I had was pulling the existing wires out of the harness under the hood for the new wires. I ended up breaking one of the retaining clips on the harness but everything works great. You will have to take it to the dealer for a flash to get the wiper & defroster to work.
