i have only the shift light and was wondering how do i install it. there is red, black, and green wires. i know the red and black ..but im curious about the green.where does that go? any step by step? or is it really easy? thanks

 

come on sonny! try hooking it up to the distributor, the blue wire coming off of it or b15 at the ecu
what kind do you have, i can hook it up for you

 

it should tell you in the instructions that came with it but for me the blue wire went to my distributer but you gotta know which wire to slipce it too.

 

if you bought the shift light only, you did get the rpm pill with it right?

you attatch the green wire to the pill then goes to the tach lead wire which is the BLUE wire
