autometer help...

[AA02gt]

i bought a 2002 mustang gt. the guy before me had put an autometer quick-lite on the pillar. the rpm activated module is up under my pedals. i have been trying to figure out how to make this thing work. the shift light flashes at me when i turn on the car. i thought the pill might be bad so i bough new pills, didnt fix the problem. i noticed from the module there are a red, yellow and green wire running towards my deck... another white/ black wire runs up towards the module ( i think it is the ground and the power to the light). basically i have no idea how to fix this... anyone know anything about wiring one of these up?? any help would be apreciated. thanks

Trace the green wire first ! Black and white is ground....red is live, yellow is constant power, and green is to the tach or a switch somewhere in the dash, mayby even to the computer or dash.....Just my 2 cents...i ran my green wire straight to the pcm. So trace the green first and let us know were it goes...!
