Okay I have been searching all night and I've just gotten confused, does anyone know of a good write up for me. I just want a simple toggle switch for my fan. Nothing fancy. Just on and off. I have a 95.

Thats 15 pages all about it. I have read through it before and I want to say no one could get it to work on the '95. Nonetheless its a pretty good write up.

Check 94xjsport94. His write up is the most simple of all. Only two wires that's it

That's what I am looking for. Now if only I could find it

Splice into the dark blue with pink stripe wire, pin #31.

go for the second option: runs normal/off completely/manual on

i did it and would have an xj without it!! should be the first mod anyone does. lol

I'm still not sure why you guys screw around with trying to trick the PCM and tripping CELs and stuff.
Its simple...
Get a switch and relay. Wire the switch to trip the relay and splice it in to the hot wire on the fan right at the fan itself. The PCM will still work to turn it on when it is hot or the ac requires, but your switch will allow you to run the fan when you want. If you power the switch to trip the relay with a "always hot" wire, you can run the fan with the engine off for a few minutes to keep air flowing over the motor. Works great with hood vents.
If you power the switch with an ignition controlled power source, you wont have to worry about forgetting to turn it off.
This works with ALL model years and I have yet to see it trigger a CEl.

LEAVE the PCM ALONE!

Thank you, that is what I want to do. As I said in the first post, I just want to switch it on when I want. Does anyone have awrite up to that. No "tricking the pcm"

? And my write up apparently won't make the fan run then huh... 2 wires and no relays with the same function as all your relay junk.

ohio95xj

No, it will work. I haven't done it yet. I just wanthe most simple one possible, because wiring isn't really my thing

cleenrob

his way is pretty easy. i did it in a bout an hour. the only hard par for me was climbing up under the dash and running the wires to the switch

94XjSport94

Yep. I could easily do this mod in 30 min on another XJ.

ohio95xj

okay, you guys talked me in to it. I'm gonna do it your way

I have seen some write ups and they make it really too complicated with relays, bridges, fuses etc, this one is so simple. Only two wires and a switch, Third wire if u want on-off-on switch.
And if ur worried about CELs. Get a diode from radio shack. It's so simple really

Jamison

Yes, it will work on SOME XJs. Not on mine. The fan runs fine until you switch on the A/C and it trips a CEL every time. Diode or no diode, I get a CEL. It took me no longer to run my relay than it did for you to dig out the correct pink/blue wire. Same time to run the switch. To each his own. I tried the "trick the PCM route" with the pink/blue wire to ground. My Jeep didn't like it, so I just wired in a switch and now I can run the fan anytime I want and it still comes on with the A/C when its supposed to and also when the temp reaches 218, even if my switch is off.
