Alright Guys....bit of help needed.

I have a Alpha Sequential Shift Light to fit into my Series 2 RST but I've forgot where to connect the wires to (I don't have the instructions).

There are three wires Red / Blue / Green

They need to be connected to three points

1. Ground
2. 12v positive Supply
3. Ignition Coil negative

Does anyone have any idea what to connet the coil negative to (I'm alright with the earth / positive supply)

I'm assuming red is the positive supply and green is earth
