If i remembered correctly when I installed mine. Green wire = RPM
Red wire = ignition
Black = ground
2 Blue = light (if you have an indiglo gauge, you'll know what i'm talking about)
2 Brown = connect w/ black (ground).
Ignition, go buy a tester @ Walmart or Autozone. cost me like 3.99 + tax (buy the one w/ the negative clamp). Get the one w/ light and a long sharp pointer. You have to take out the gauge cluster. There are two connector connected to the gauge cluster. detach that (caution: becareful, it's very hard to take out) take your time.
The RPM wire = Brown w/ white stipe (not too sure, gotta check on that, but very positive)
and for the IGNITION, used that tester ( clamp that negative to a negative ground, and then poke that pointer into those tiny slots (I think it the one on the far right w/ red wire). Remember to turn off your car, test it, turn on then off to see if the light turn off.
I'm not very good w/ words, hope it help!
