S13 ignition switch wiring

[IneedBoost]

Trying to figure out why my car won't start. Going over every possibility as to why it's not getting injector pulse. So what wires on the ignition do what?

I know the black/red is starter. The black/yellow does what? It's not connected to anything (friend custom wired the car) I've read in other places that it gets hooked up to something and runs to the Ecu to tell it that the car is starting? Correct me if I'm wrong. Any suggestions?

Give a man an answer, he'll never learn to search.
Teach a man to search and he'll have fish or someshit.

I searched this 4 months ago, plenty of info on subject.

I believe its ign relay....not sure.

I've searched and only got as far as finding out that the black/yellow wire goes to the Ecu but what pin and where is really my question.

Wouldnt a fsm help you out?

I've looked through the fsm and it looks like the black/yellow wire connects somewhere to an orange wire for ecm(eccs control module). Now to figure out what that does. The car doesn't have any of the factory wiring and something is definitely missing in order to make it run properlyhttp://i101.photobucket.com/albums/m45/Kastner2006/Screenshot_2014-06-10-07-23-02.png (http://s101.photobucket.com/user/Kastner2006/media/Screenshot_2014-06-10-07-23-02.png.html)
