I bought a hard top from a guy on craigslist its a TJ hard top but he didnt know what year it was and i dont either, i dont give a darn about the rear wiper.. but i would LIKE to have defrost... is it possible to pull the plug out of the hard top and run a wire to an individual switch without having to buy the darn harness/washer pump package with everything in it... does anyone have a schematic for that plug? how would i know which year hardtop i have?
if the top has vents behind the windows, it's 97-02 , no vents is 03 -06.
ok, so i have 97-02 hard top on my 05 jeep. so all i need to do if im reading that other thread correctly is apply power to pin 1 on the plug? and just put a switch/fuse inline then (and remember to turn it off when its defrosted..
Pin 1 gets the power & you will need a ground to pin 6. Note that the OEM uses a relay & a 40a fuse to the relay & 12g wire all the way to the back. Make sure the switch is rated at least 40a or use a relay. There are timer relays available so you might want to consider that.
First make sure the grid on the window is intact check with a meter
The stock setup has a relay a switch and uses a timer already built into the instrument cluster so if your own circuit you need some sort of timer plus a fuse and relay plus a switch. Also make sure you use large enough wire as it is a fairly high amp load.
Finally make sure it only comes on with ignition on or it might lead to accidental turn on and dead battery
The 2 big wires in rear plug are for a common ground (black) and defogger positive (black with white)
Early hard tops have vents and a 10 pin wire plug
first couple early years also have a dome light in the hard top.
late years no vents on back corners (as those jeeps had vented tailgate) and a 6 pin plug
You can get another 6 pin plug to plug in with suitable size wires from the power seat of a dodge durango
The 10 pin plug can be found under hood of dodge neon but you should put in larger wires for the defroster and they again can come from power seat plug of durango
If you run your own wires and add a switch and relay you could use the add on harness instructions to use know how to splice into instrument cluster timer but instructions are somewhat year specific and it involves pressing a connector or 2 into the instrument wiring plugs.
OK, should I check for resistance at the two plugs or continuity across each line of the grid? I have the vents, but no light.
I plan on running 12-14 AWG with a timed relay and perhaps a momentary switch (it just need to pulse once to trigger the relay correct? Or does it need to be a continuous trigger signal? ) and inline fuse
I've never used one but I'm pretty sure a momentary switch will latch the relay & the timer will take it from there. You should resistance test from the connector pins. That will test the whole circuit including the wiring to & from the element. As long as there is not infinite resistance (open circuit) you should be OK.
I was going to run it off constant actually, that way I could reach in, hit the switch and defrost even with the vehicle off since it will be outside all winter.. Fused within a foot of the battery and then quick disconnect connectors at the rest where the factory plug would be so I can disconnect it when I take the top off
I have the factory soft top on my 2005 Wrangler X but would like to add the hard top. Is there a factory harness or wiring package that would make the proper connection easy? I would appreciate the correct name and part number. Thanks
