I know how to use one I just dont have one. And for some reason I really can't comprehend electrical stuff, relays, fuses. Seems waaaay overly complicated for no real reason. Get over here and do it for me!! lol but seriously I put the original relay in and got it to clear the CEL so maybe I got the wrong relay, it looked identical so who knows.

I'm curious why I couldn't splice into the wires that go to the Efan. The small pigtail that comes off the fan and connects into another harness that goes to no mans land from there. That little section of wire to the fan should be a ground and power? So why not splice into them and wire it straight to a switch? Obviously I must add a fuse or something from I know but I don't see any issues with it and it should function as normal as it does now but I get full control.

Either you're actually in 4WD (sometimes the linkage is out of adjustment) or the U joints up front are going out. You'll want to put the Jeep up on jack stands and start turning things. Start with just the front axle on stands so both tires are off the ground and rotate the tires by hand.

Wait, what? You're trying to splice into that circuit and the CEL came on after a relay died? Or what? Super confused...

no no sorry lol. All I did was replace the relay and the CEL came on and I couldn't get it to go off. Put my old one back in and managed to clear the CEL, but the fan ofcourse still does not work properly (Fan comes on with AC/Defrost intermittently, but does not come at 217F). What I was asking was if it would be possible to splice into the wires that come directly off the Efan and wire them to a switch. Allowing it to function "normally" but still giving me the ability to manually turn it on.

Oh yeah and I read that Oil thread you have, really freaking helpful and I'm glad someone finally did some good in depth research for a good oil for these motors. I've heard the Rotella rumors but you have convinced me lol. No more Castrol ha

Ohhhh. You're sure the replacement relay is good? Yes such a mod has been done, I've seen schematics on here and NAXJA for that. But really I'd focus on getting that fixed first before modifying it, it'd be pretty ****ty to overheat because you were distracted and didn't hit a switch lol.

Thank's but I'd hardly consider it in-depth lol. Glad you liked it

Well it should be good, I bought it from Autozone and they had no idea how to look it up so they found one that looked similar. The main reason I'd like to have the ability to manually turn it on is for wheeling. I usually have to drive with my hood popped open on the trails to keep it under 220 atleast. And thats with the fan kicking on every 30 seconds or so for a few seconds at a time.

Has anyone removed the rain gutter trim on a 97-01' xj? I can see the metal clips, is it as easy as simply pushing from the bottom like on pre-96' xjs? Thanks (borrowed picture of a pre 96' trim)

Why would you want to? It covers a pinch seam.

1. I want to clean the rust that is forming under the trim.
2. I want to replace the trim with one from the junkyard that isn't smashed like mine.

Yes, that's pin 12 on connector A of the PCM

OBD-I and OBD-II PCMs are very different, there are more differences within the generations but I'm not sure if that extends to the pinouts. You pretty much need exact information for your year.
