Hi, I've been looking for the ECU wiring pinout for my K15B engine. Been searching and asking everywhere for it but no luck, would anyone have a copy of the wiring pinout diagram.
I'm currently wanting to rewire the wiring harnesses from the ECU to the transmission. Having the diagram will really help out lots. Thanks

What are you trying to achieve?
The ECU controls the Engine.
The BCU (Body Control Unit) and TCM (on A/T systems) and 4WD module control the rest of the vehicle including the transmission. However the bulk of the communication is now CANBUS so is a data link, not simple sensor signals.

Hi, thanks for the info.
I've bought a K15B engine together with the 4 speed A/T transmission but the wires has all been cut therefore I would like to figure out what each wire connects to.
Thanks !
I've attached a picture of the ECU/BCU and the cut wires.

I hate to be the bearer of bad news, but, the wiring is going to be the least of your problems - you're not going to get that running without the immobilizer & keys from the Jimny that ECM came from, or another immobilizer & key set AND a way to program them to one another.
You're also going to need the TCM, BCM and pretty much every other electronic controller the "donor" car had fitted because they're going to look for one another and generate fault codes when they can't find the missing controllers.

HI, thank you so much for the much needed info!
I've currently managed to rewired the ECU wrings, bypass the immobilizer and the BCM connected. However i was only aware of the TCM after you mentioned it. I then went looking for one. I'll attached an image, would you kindly help me to confirm that this is the TCM for the engine. thanks you!

Thanks for the confirmation Martin!
By the way do you know if the wiring harness for the TCU has a part number so that I can look for one online? Or do I have to figure the wiring out.
