Hello everyone,
I recently purchased a Proform shift light Proform 67005C, Proform Adjustable RPM Shift Lights | Proform and I'm having an issue with it not working. I connected the red wire to 12v ign, black to ground and green wire to leading coil #1 on the negative. Once I start the car the light comes on for 2 seconds like it should. Adjusted it to 3k and no light, and yes I cut the brown and orange wires. Since I have a Microtech LT9c I tried connecting the green wire to the tach out on the microtech, still no good. Any ideas?

Thanks
Joe
