Folks, I re,moved an Astro Start from the Aurora and now I am installing it in the Bonnie. These are dealer install only type devices so you know what I'm up against. Here'* where I'm at. I need to figure out which wire I take a green black (the astro start wire) to. It went to a yellow black on the Rora'* #1 fuel injector. So, using commom sense, I figure it should go to the #1 fuel injector on the Bonnie, but of course it doesn't have a yellow black wire to it. Of the two wires I need to figure out which one is right.

I think tonight I will use my multi meter to see what happens when I turn on the ignition in the Rora and compare this to the Bonnie??? Make any sense?

On the injector..one wire should be ground, the other should be power. I'd bet it was on the power.

Fuel Injector Connection.

Looks like the wire that you need is a nice pretty pink.

Thanks folks I just can't thnk what this hookup really does, but I'm going to go for the pink!

I think it'* similar to the tach wire. When the system sees an injector pulse then it knows the engine is running.
