Does anyone have a engine ECU wiring diagram/pin diagram for the JK?

Big please!!!

 

You mean the pin-out from the ECU? The entire engine harness? Need more specifics.

 

I need all PIN's with there details...

If not, then:

- Load (MAP sensor)
- Throttle Pos
- Crankshaft sensor
- Power 12V+
- Earth
- Coolant temp sensor
- Intake air temp sensor

Thats all for now!

 

I guess not then........ Thanks for the feedback!

 

I have the manual, I just cannot figure out how to save just the images. Got a way for me to send you a 170meg file?

 

Hey rabid, what section is it, I can try too.

 

Good luck finding that on a car

I know you mean ground, but 'earth' is not an interchangeable term. Negative, Return, VSS would be replaceable. I suspect you have little idea of what you are messing with. Looks to me like you are putting in a uniChips box or gauges or something.

Good luck with that too. There isn't one for this car. Well, there is kinda, but its a 20V proprietary iirc, so nothing you hook to it will read it correctly. There is no traditional throttle pos analog signal.

The crank sensor (if the 3.8L even has one) is not a normal evenly pulsed signal. If you are trying to get RPM to drive a gauge you may have some problems with that.

Sounds like you need more then wiring diagrams.

 

Este,

That was a mouth full. Instead of commenting like that, why didn’t you just answer by saying, yes you have a PIN out diagram or know you don’t have? I’ll take it as a bit of humor.

Well, were I come from we call it earth, if it blows your hair back, GROUND will also do. Or lets call it Battery Negative, but a REFERENCE GROUND is the correct one I’m looking for. Also, a crank or camshaft signal will do and IT WILL have any one of them… you are right, there isn’t any ANALOG (definitely not analog) signals for the TPS, also there has never been one in history. If it’s not a voltage between 0-5V or 0-12V, it will be DIGITAL (Hall Effect signal, if you know what that means?) but not ANALOG….

Yes, I want to UNICHIP it. Also called Piggy Back computing.

Thanks for the other guy’s that’s trying to help
