3W-75US ignition module setup
 

I'm in the process of completing my first gasser, an Aviation Models 30% Yak. I've installed the 3W-75US & mounted the ignition module, but can't figure out where all the wires go. There are the obvious, the spark plug wire, the black/yellow/red connection for the pickup and the brown (black?)/red wire for the battery connection, but that leaves two sets of wires, a black/red & a yellow/yellow.

The ignition came with an LED, which I assume connects to one of the remaining wire sets, but which one, and what do I do with the remaining wire set?

Any insights would be greatly appreciated. Thanks!

The Yellow wire is for using the 3W tach. I have one and it works great. The other wire is for the led. I used a grommet that I mounted in the fuse and then put the led inside the grommet.
