Righto, next question ....

So I think the majority of the wiring is done now, and I have it to the stage the motor is cranking over. I think If I put fuel in, it might even start!

Now on the GMPP fuse box is a MIL light, which comes on when the key is turned on. Should go off when engine starts. The bulkhead harness also has an output for this same light signal, which I wired thru a small dash indicator light and then to earth. But it does not light up.

Any thoughts on this? Is it wired properly?

Similarly I have signals coming from the bulkhead connector that go to my speedhut tacho and speedo. Any notes on correct way of hooking these up? I have just run them as signals in to these gauges, not sure if a ground for the signal is required? The gauges do run independent power.

Thanks
