Rear defrost

Hello,

Has anyone tried wiring up their defrost to a YJ that wasn't configured for it? Are there any kits for this? Just wondering before I went at it myself to save some grief.

i'll look it up after dinner and get back to you. i sold my top and am wired for a heater. i think the switch is timed but not sure. i will get back to you. also, do you have a rear windshield wiper? mike

yep, trailer. all of the jeeps i have owned have had wiring in the rear for hard top use. do you have carpeting in the tub? if so, pull it back and look behind it.

Yes there is a timer. It's a red relay by the drivers left foot just ahead of the door.
The correct harness can be bought from ebay. That's where I got mine when I bought a hardtop w/defrost and wipe.
It plugs into your factory harness.

89 YJ Rear Defogger Wiring Diagram

Here is the rear window defogger wiring diagram for my 89YJ. Page 54 shows the factory plug is four connectors, all female. It should be under the carpeting near the driver side rear taillight.

If I can find the picture of mine I will upload as well.

I am trying to find the wiring diagram for the 10 pin connector for the 1990-ish hardtop I recently picked up that has the rwd and wiper. Since the fog light switch is in use, I'm also trying to figure out where/how to mount the switch for the rear wiper.

Alright, so I have the two female connectors. The one is up by my parking break, and the other is on the top. The connector are both different sizes, don't know if they should match up or not. The top is from 1989, and the jeep is a 1995.
