Both of my isspro's have 4 wires. I have a set of directions for that, but not a 3 wire. Is the tach backlit??

I guess I can't help then. Maybe call Isspro direct and ask for Don Wendlick. 1-800-888-8065 and his extension is 3402. He is the tech guy and has helped me. He has a 1st gen he bought new. :D
