And most of the sensors on the yj's engine ran off 9 volts, tj's were mostly 5 volts if I remember correctly, so you might be having to replace some sending units and other sensors off the engine, transmission, etc.

I just pulled the harness off of a motor i pulled from a 97 TJ, I had to cut the wire to the alternator so idk if its any good to you. I could also get the ECM, too PM me if your interested.

can i use the comp from a auto or do i need one from 5spd?

 

[RnEmOvr]

ECU and harness have been ordered, i finally got a job so things should start rolling good now

 

[RnEmOvr]

ECU and Harness came in this week!! didnt get any pics but i took the YJ harness out and put the TJ harness in today, also ordered all the sensors and stuff that was different from te TJ system, will start taking pics tomorrow

HEy RnEmOvr, Where did you get the harness, i need to find one to swap out my 4.0 and put in an LS1.. are your going with a stock harness or custom made?

 

[RnEmOvr]

im doing stock harness, i found forum member who was selling one,


also i got my wiring diagrams (if anyone needs copy let me know) so wiring should be finished this week

 

[RnEmOvr]

well i did some more wiring this week, dont have any pics wire are wires, i forgot my tools at work so i wasnt able to finish them up tonight, i going to go up tomorrow and get them, only parts i need that i cant find (reward if you find them) is adapter for the fuel lines (unless i need new ones) and a vacume line,

 

[RnEmOvr]

few pics, will get more

What harness are you using? If its a tj harness, it should just plug in and work. You may have had to change some sensors, but thats it.

 

[RnEmOvr]

its a TJ harness but mine has the rectangle plugs at top center as where this once has 2 square ones over by battery

 

[Dmax5er]

GEEEEZZZ!!! looks like spaghetti,, ill stick to body work.........

 

[RnEmOvr]

ive done both, they both suck about the same

 

[RnEmOvr]

well finished up the harness, started with what you see sitting on the tire in above pics, then to this

then finished up with this, (from first plug back was cut off)

 

[RnEmOvr]

no pics but i put throttle body, alt, CPS, and some other sensors on and started on SYE for t/c

 

[gaucho919]

looks sweet man, Ive been thinking of swapping out my 4.0 for a 5.2, keep posting nice pics

 

[RnEmOvr]

ok well got starter and alt mounted, fuel lines came in, it now turns over but wont start, throwing few codes,

42*Auto Shutdown Relay Ctrl Circuit; or No ASD Relay Output Voltage at PCM; or Fuel Pump Relay Control Circuit; or Fuel Level Sending Unit Volts Too High (or Too Low); or Fuel Level Unit No Change Over MilesAn open or shorted condition detected in the auto shutdown relay circuit; or An open condition detected in the ASD relay output circuit; or An open or shorted condition detected in the fuel pump relay control circuit; or Shorted (or open) circuit between PCM and fuel gauge sending unit; or No movement of fuel level sender detected

24**Throttle Position Sensor Voltage High (or Low); or TPS Voltage Does Not Agree With MAPThrottle position sensor input above the maximum (or below the minimum) acceptable voltage; or TPS signal does not correlate to MAP sensor

31**EVAP Purge Solenoid Circuit; or EVAP Purge Flow Monitor FailureAn open or shorted condition detected in the duty cycle purge solenoid circuit; or Insufficient or excessive vapor flow detected during evaporative emission system operation

* = This DTC will not cause the Check Engine Lamp (MIL) to illuminate. However, if another problem causes the MIL to illuminate, and this code is identified when you display all of the codes, at least you will know what it means.
** = The Check Engine Lamp (MIL) will illuminate during engine operation if this DTC is recorded.
*** = Generator Lamp will also be illuminated if this DTC is recorded.​

You're so close man. This is always the most stressful part because you are so close to the end you don't want to stop working on it until you finish the job. Good luck, post up a vid when you get 'er runnin'!

 

[RnEmOvr]

o i will, the neighbors have been pissed that its been sitting so long, so i will be sure to fire it up (with the open headers) and make sure to get video



although it is nice to be able to work 20 mins then "damn, another parts run"
