I can't comment about the TB but apparently swapping the jeep injectors out for ones from a neon is a big improvement. It's one of the add ons I'll be doing with my swap.

Yes x2 on the injectors. 4 holes not 1. The 4.0 head and most 258 blocks were 1/2 inch bolts. There were 2 or 3 years where they went 7/16 thus allowing a bit of potential movement of the gasket!

I have been reading this thread, trying to glean every speck of info I can! Getting ready to do this swap in my son's CJ5. We picked up a donor '97 XJ for $500. I haven't finished reading yet, and I know I'm jumping ahead, but the research is fresh in my mind. For anyone wanting clarification on the VSS, the specific VSS is for a '91 YJ with the 4.0 -OR- 1988 Dodge Dakota, 2WD, with the 3.9L. They are the same part number at AZ. Other late '80s model Dakotas may work, but you'd have to check.

Here are some more links for the injector swap as JW mentions. Lots of info in the Cherokee Tech forum regarding this. This is a very good upgrade, and you can find the injectors, cleaned and ready to go, on Ebay for about $100 a set of 6.

Late 80s Dodge ramchargers have the vss also. They all still need the adaptor for the spedo cable end to go from 3/4" to 7/8" that the CJ uses. I get them both and screw the adaptor on it and they dont know it didnt come that way at the pick a part yard. I think I picked up 3 of them in one trip with the adaptors for 7.99 each.

'86... please go into more detail about the adapter. I think I read that it comes from the cruise control, but my son didn't find anything today at the JY. He brought home an entire cruise control unit from an XJ! Exactly where do I find it?



Also, for clarification, since our 4.0 came from an automatic XJ, I have to find a flywheel from a manual 4.0??? This will bolt up to a T18.

Skerr, I was told from the old cj offroad boards that they were only on the early XJs with the Renix 4.0. I am lazy so I look for a Renix 4.0 (a easy way to tell a Renix is the throttle body only has 3 mounting bolts to the intake manifold, obd1 and obd2 has 4. I look for one that someone else has pulled the dash cluster out. Find the spedo cable and follow it down about 12" and it will unscrew from the cruse control sensor, the adaptor will be on the cable or on the sensor. Just a small black plastic adaptor that is threaded on the inside 3/4" and threaded on the outside 7/8". I just take it off and screw it on the speed sensor and they wont know that it is 2 parts. Hesco's is aluminum in the picture but you will see what the adaptor looks like. Easy to find around here as there are a lot of XJs in the yards in the Denver area. http://www.hesco.us/shop.asp?action=showpic&id=50392&header=false

Skerr, you know that the 97 is obd2 right? more that likely a 97 will have a skim. Do a search on how to defeat it before you take the engine out if it is still in and running.

Okay... thanks. Our yards are "Jeep poor", but I'll look closer and see if I can find one. If not, then I'll buy one from hesco.

A buddy bought the whole '97 XJ for the engine. He was going to put it in his YJ. He heard it run and pulled it. Then he decided to go SBC. I bought the XJ, minus the engine, for a parts car for another son's XJ build (I've got 4 sons!). When the 258 started pukin oil we decided to go 4.0, and I bought the engine. So I ended up with the whole car. We're prepping the engine to crank it on the trailer, where it's strapped down. I do know it's OBDII, but I WASN'T intimidated. Now we're trying to find the "5 to fire", and it ain't working out so well!

-SO-

Would life improve if I find an OBDI ECM?

Can I use the OBDII harness, or do I need to pull the harness as well?

Anybody have a diagram of the '97 XJ fuse/junction box... specifically the pin outs?

Do I have to find the flywheel from a manual 4.0?

TIA...

Anyone have any good tips on thinning the wiring harness? There are a lot of wires not being used. I'd like to clean them up. I have a FSM, but I'm an electrical wiring retard. Feel free to talk to me like I'm an idiot.

Also, I'm still having some running issues. I'm either going to figure it out or swap in a 350 and be done with it. But, I'd prefer to keep the 4.0L. I'm sure it's a distributor thing. It just sputters and pops under throttle. Timing light says everything is fine. But the throttle response says otherwise.

HELP!

I did this about six months ago. What I did, is got a couple of wiring diagrams, marked them out, to determine which wires need to go in which ones need to stay. Wires that go to sensors that are needed in the swap Obviously need to stay, along with grounds. Everything else can be traced back to the Computer, and cut. I left enough wire at the harness to reconnect any wires that I may have screwed up on.

Just take your time, and leave enough wire harness ends to patch them back in if you screwup. Good luck!

Thanks. I think that's my plan. It's always nerve racking when you start cutting wires.

The damn thing is running right now. Not well, but running. I don't want to screw anything up.

If I can figure out the wiring harness thinning and the timing issue, I'm going to be a very happy camper!
