Auto VS Manual starter wiring

[crazynick505]

G'day guys,

I have a manual converted VR4 and have just recently swapped in an engine harness from a factory manual. (was cleaning up old crusty wiring)

The 4-pin plug under the fuse box that connected to the starter motor used to have 3 pins, whereas the manual engine loom seems to only have 2 and is missing what I assume is the signal wire to the starter to actually turn it on.

My question is, if the manual engine loom doesn't have a starter signal in it anywhere, where does that signal come from? I've been poking around but cant seem to probe anything in that fusebox area or under the dash that flicks to 12v when trying to start the car.

has anyone come across this before?

Plug from the starter's side:

Plug from the manual engine harness side: (upside down, missing the thick Black/yellow wire)

Also if anyone happens to know where a wiring diagram for this kinda stuff would be, that may help out too
I'll keep looking though

Wiring should be the same for the 6a13a sohc. Will send it in a sec

So I traced the starter signal from the key barrel, through the remote start module of my alarm system and back through to Pin D1 of the ECU
Apparently meant for the old A/T inhibitor switch. While my loom is apart, I'm assuming I'll be all sweet to just run a wire from that pin back to the plug I pictured above to get everything going
