Get yourself a set of FSM's from ebay to get the electrical diagrams. Makes it too easy. Just pay attention when you do it. I missed a wire or two and it caused a headache for a day or two.
I'm using the Dakota bellhousing and it works great.

x2, service manuals for the yj and the donor are essential. Wiring really isn't that hard after you study the diagrams and start digging in. Good luck with your swap!

Thanks!

I'm really getting antsy here... Can't find a full 5.2/5.9 that's manual. I have another quick question because it seems easier to find the computers for manual transmission vehicles/wiring harnesses, but easier to find the engines out of automatics.

Can I take an Engine out of an automatic, throw on a Manual transmission computer and wiring harness without too much trouble?

Depending on year, it may or may not.
My PCM stores a code for no transmission info, but doesn't throw a check engine light.

My current situation is that I have the chance to get a 95 5.2L out of a Grand Cherokee (which came automatic) with accessories for a very good price. I'm just thinking of grabbing a 94-95 Dodge truck's wiring harness and computer that had a standard transmission and splicing the Jeep's harness into the Dodge's. That's why I'm curious if this will work.

Just gotta find the harness and computer.

Get a same year PCM and you should be good to go.
Not sure that you would need a different harness...I didn't.

My 5.9 engine came from a 96 auto. I used a 5.2 manual wiring harness from a 95, and a 5.9 manual computer from a 95. The parts are very interchangeable between all the various configurations, but I would recommend you keep it simple and use a manual harness and computer if you're using the ax-15.

No adapters are needed to run an ax-15 behind any magnum mopar v8, just a dakota bellhousing from the mid 90s.

Anyone have a good reliable source in which to find a Computer and Wiring harness for a Manual transmission? It's really tough to find a truck with a standard transmission here in town to root a wiring harness out of.

Got my junk from the local "u pull it" junk yard. Manuals are pretty common in 5.2 dodge ram trucks.

I called everywhere... nobody even had a 5.2l in stock, even called places 2 hours away.

I had tried Car-part.com before, never came up with anything... until I realized my mistake... I had it set for only AZ.

Went nationwide search, I have a computer and wiring harness being shipped to me out of a 94 Dodge Ram.

Just going to pick up the actual engine in the next day or two.

Then commences rebuilding everything.

You may be suprised.
I pulled mine apart and found the cylinders to be in great shape.
I just cleaned the pistons and installed new rings.
On the negative, it needed a crank, but we have a crank rebuilder locally that is pretty cheap. Overall, I didn't have any block machine costs.

^this, I rebuilt mine completely, but you may can get away with just doing new bearings and rings and a good cleaning.

Alright, well talk (and money) has finally turned into an engine being in my back-yard. Looks pretty solid, the AC line have been snipped, the 2 pvc valves are missing, and just a bunch of the wiring harness is still attached, cut at the end.



Going to find an engine stand, and start dismantling/cleaning everything. Got my Computer and wiring harness in the mail, so waiting on those.

Gonna wait until Tuesday, and purchase a rebuild kit for the engine. Anybody have a good priced one that they're happy with?
