did you loose your instructions or something?

you should have 3 wires, a black a red and another onother one

red goes to a 12V source such at the blue power wire to your HU
black goes to a good ground (I bolted mine to the firewall)
the other wires runs to the RPM wire that runs to the ECU. On mine it's a solid green wire, but i'm not sure what it is on your 2nd gen.

hey thank you for the info. I never had the instructions but there are 4 wires. i know that the red is hot, black is ground, green goes to the signal, and white goes to the lights. JoBoy
