If it came factory in one it'll go in the other..

 

You would have to swap the engine, wiring harnesses, cooling system, and I think the trans and transfercase due to different spline count.

Basically anytuing that's different, switch it out. Factory engine swaps are relatively easy if you have the donor vehicle right there, its when you start crossbreeding it gets tricky haha

 

Ok, so I swapped my injectors for 703s last night, and it ran great...until I started it up this morning. Now it's throwing the same code P0203 open circuit injector 3. That leads me to believe its the plug. How can I fix this? Electronics on a car is my least favorite part. Help!

 

Someone would need to second this but I think you can swap the writing to another one but it's a specif one. I coulda be wrong be so least correct me if anything

 

Unless he tries to put an I6 in a '84-86 XJ. That requires firewall modification.

 

my local autozone can get one, but how do i wire 'em up? which color is pos, which neg?

 

Well... I wanna put speakers in the back of my xj and im not sure where to run the wires?
And I'm putting the wiring kit for trailer lights and I want to run them to the out side permanently without just throwing them out the hatch. Any suggestions? Plz and thank you

Run the wires through the trim on the inside, it all comes off. For the towing lights, wire it from underneath? Anyways no one is going to email you so goodluck.

 

Ok renix xj. Low idle crappy throttle and tranny response, truck will eventually die. tps?

 

TPS, CPS, IAC, CTS. Try unplugging CTS and see if it helps. That's the easiest test. It's right here behind the #1 freeze plug:

 

My turn. Renix. My MAT/IAT sensor has continuity to ground on both pins and has varying resistance across all pins in this connector:



My question is: What the ****?

 

You'll need the frame horns for the 4.0 (what the engine mounts bolt to), wiring harness, radiator and front plate (4.0 radiator sits much closer to the grill, 2.5 radiator might work, but not in its stock position. Not enough room), as said before you'll need the tranny, transfercase (unless you want to change the one you have to a 23 spline), and both driveshafts as well if you're changing from manual to auto.

 

I'll have to explore with a volt meter. Not the cts

 

Isnt that the NSS wireing connector?

 

Appears to be. It runs to the trans.
