Hi all, spent a good amount of time figuring out what wires in the junctions both under the stereo and under the fuse box connect to, I think I have got them all, most by tracing the wire back to the ecu plugs and using the pinout provided by Kitty as a reference, or doing continuity tests to the plugs in the engine bay

I will post up my results however I have noticed the absence of one wire, Tachometer.

Ive double checked all the wires going to the ecu to the diagram, I've also noticed there is no tach output listed on the pinout

can someone help?

I think the tacho signal comes from the Ignition Failure Sensor output, look for that.
