ok so i got the raptor shift light today in the mail. hooked it all up the green wire to the green wire with the white stripe the red to a power sorce and black to a ground. it went threw the test fine and took it out for a test run. got the car up to6500 and no light came on.i re did the tach wire thinking that was the problem tried a differnt connector and still nothing. any ideas? your supposed touse the green wire on thepcm in slot26.

 

How do you set that to the right RPM's?

 

nick your suspose to set the rpms on the actual raptor device. Did you do it?

 

yes sir. i did everything it said to do. i might not have the right wire for the tac hooked up. i cant fnd any other site to show how to wire it up.

 

well i hooked it to a dark green wire with white stripe. its supposed to be the light green with white stripe. fixed that. but the dark green with white got cut in half didnt fix it right away an now the light sits there and flickers on and off. still wont come on at set rpm. errrrrrrrr making me mad over here.

 

hmm...are you doing anything tonight? I can help you out with it if you want me to or try to help because i wanna get one eventually

 

do you have the cylinder number set correctly? I think you have to set it to one cyilnder for our cars, can't remeber....

 

i thought you had to have it set for 8 cyl. but ill try it on 1 cyl. that would be weird if i have to have it set at 1 cyl.

 

yea for our cars you do have to have it set to 1 cyl mode

 

it has to do with how the ECU tells the cylinders to fire. The raptor is expecting you (on 8 cylinder mode) to provide it with 8 pulses of voltage per revolution. The ECU is sending out a signal on the wire your tapped into only once per revolution... so the raptor never thinks your getting to the correct RPM.
