I have it parked next to my 89 Comanche which runs. I swapped the relays over, no change. No fuel pressure at the test port. The Comanche has the resistor, but the Cherokee does not have it. There is some old audiovox security system box there. I followed the leads on it, they are disconnected at one end, the other end goes to a key box in the truck. I don't have the key, neither did the previous owner. It ran fine yesterday. I can't find the resistor!

You don't NEED the resistor. Your fuel pump coulda taken a dump then.

Got voltage back there when the key is first turned to On?

What color wire should I be checking for voltage? Can I check it where it runs past the drivers seat? I have the seats out.

I guess I'm just asking if it will be worth my time to drop it in. about 250k on the 8.25 axle. Thoughts or opinions?
It would be a worthwhile swap regardless if spline count, as long as gear ratio is the same

I did exactly what you are wanting to do. I did rub initially, but I ended up putting on ZJ front lower control arms. They are welded boxed tubing and built with an offset. I no longer rub at full lock, may be worth looking into.

And the upgrade path to rear discs is super easy.

Not necessarily. I would rather run a good working D35 than drop in an 27-spline that was run without fluid or other unknown history and potential damage... some diligence is due.

About as easy as a D35!

How does one keep wheels from being stuck when you take the lug nuts off?
Also is there a trick to taking them off when they're stuck? Trying to rotate the tires on my wife's tj and the front wheels are being big fat *****es lol
