Shift Light, How-To Options

[Defgeph]

OK here goes.

I hooked mine up to a 3sgteRC.
Not sure if the 7a and 5s are the same.

The unit has three wires. Black, Red, Green(in mycase)

Black goes to ground. The red goes to positve, like the cig lighter.
Green or signal wire connects to the solid black wire on your ignitor in the engine bay.

After ur done you should have something like this


The end

i THINK the black wire goes directly from the ignitor to your tach.. so if you splice into that, it should work.
