Jimny JB23 ecm wiring diagram needed!

Hi all,

I have a JDM Jimny JB23 engine/trans (K6A, 660cc turbo, 5 speed) that I purchased off Ebay here in the states.
It came with the ECM and most of the wiring harness, but the wiring was pretty chopped up when they pulled the engine.
I am in the process of installing the engine in a '72 LJ10, replacing the existing 2-stroke 360cc twin that has a failing crank. I wouldn't be replacing this engine, but I am unable to find sufficient parts to rebuild it.

Anyways, I have not been able to find any wiring diagrams for the K6A engine used in the JB23 model. I believe that besides Japan, they were also sold in the U.K. Maybe the later model Suzuki Cappucino would also have basically the same wiring between the ECM and the engine.
Is there anyone out there that can help me with this? I am in desperate need of a good wiring diagram, because I am in the final stages of installing this engine.

Thank you in advance,

Tom H.

I would imagine one of our members Rhinoman might be able to help with this, he's the resident electrical guru :thumbup: I'm sure he will be along shortly.

Could have a look on his website to see if there's anything on there already though??

I don't have a wiring diagram and they weren't sold in the UK, I don't think they were sold in Europe at all so I can't get the data from the Suzuki Service Portal either. If its a Denso ECU then it may have the pin designations printed on the circuit board.

I don't have a cappucino manual here, but if you get really desperate there is what looks like a complete manual here:

http://www.suzuki-cappuccino.com/manual ... /index.htm

But you have to pay £12 (about $20) to join and view it...

Ive got most of the parts numbers and diagrams but no electrical diagram :(
