G13BB wiring was created by gsalini
Evening all.
Im doing a turbo project for my G13BB SOHC engine. Unfortunately for me I cant find any wiring diagrams for my exact model of car. Its a 2004 spanish soft top with the previously mentioned engine model. Whats unusual is that it has both cam and crank sensors but the cam is a hall effect 3 wire sensor and the crank is a VR 2 wire sensor. Can anyone point me in the direction of where the crank cables go to on the ECU?

I would use the cam for ignition alterations but it seems my G13BB uses the crank as primary!

Any help at all would be great. Thanks

Yes Neil I'm on Eastern side Australia and only have a cam angle sensor no crank angle sensor. Jimny hasn't produced any wacky idle symptoms yet, since putting in a new fuel pump. Owl

Yep Neil, I hear your pain,  My Jimny gave me a familiar fault once more,  driving down the freeway sitting on 85 to 90kms per hour,  engine decides to shut off, and come back on ,  back and forth in that manner for about 10 to 15 secs,  and then I stopped at the traffic lights and it idles nicely and drives off as if nothing is wrong. No check engine light but the engine management hiccups to the extreme ?? Has to be the ECU epilepsy. 

There is other very subtle intermittent symptoms,  very faint misfire, run-on feel (its not the IAC sensor),  engine lacking power, high fuel consumption, and at the severe end it engine shuts down and then comes back.  Always starts ok. And it runs really smooth at times.
