Does anyone know what the 4 ignition wires that go from the barrell to the blue multiplug are?

I'm trying to wire in my remote start but cant find an ignition wiring diagram

 

They are

black/white
black/blue
black/yellow
and black

 

im the same the only help i got is at the moment is the black is an earth i think

 

You need a circuit tester: mine was about £2 from a local carshop, brass barrel with a point on the end, (a bulb in the barrel lights if you find a live), and a metre of wire on the other end with a crocodile clip on it's end.

With that, you clip the croc to a KNOWN good earth, (sometimes I extend it right back to battery earthwith a length of wire when working inside the car), and use the point on the brass barrel to probe wires to find permanent live, (eg: hazards), switched accessory live (eg: radio), switched ignition live, (everything), and starter only live.

Worth loads to me.
