hey guys bought a raptor shift light, its grounded, and powered right but for some reason when i rev it it bounces of a rev limiter at like six grand. its a zc dohc the light signal is ran of the blue wire off the dizzy which is the negative wire i believe what could it be? is the black and yellow wire the negative? anything else anyone can think of? any help appreciated.

 

this might be a weird question....


does the light not turn on when free revving it in the driveway?

try driving it down the street. those funky brand gauges sometimes dont work unless in motion.


also, check the bulb, sometimes they burnout during installation if you dont run an inline fuse.

it revs in driveway but ends up hitting a rev limiter or someething. it works in motion buy only till 6000 rpm, the bulb is good, i was right on the blue wire being the negative wire right? i am kind of lost.

 

ITS OKAY IF IT LIGHTS

IF ITS CEL THEN WORRY

POWER IS EVERYTHING

DO NOT LET LIGHTS FOOL U

MAY BE A SHORT CIRCUIT

EITHER SERIES OR PARALLEL CIRCUIT

CHECK DIAGRAMS

 

i dont understand a thing you just said, anyone else?

 

check wiring schematics
and obtain voltmeter

check series and parallel short circuits

Dude, wtf?

 

ive got a raptor in my mustang and it works great, you just have to hook the signal up to the right signal source...

high quality part and works great if installed correctly... just find a pinout on the connector for you dizzy and find your tach signal... or do like i did and tap off of the signal wire leaving your ECU...

 

can anyone tell me what color the wire for tach signal coming off the ecu is?

 

anyone?

 

Why don't you search a pin out for your ecu, it will tell you in the pin out diagram...

 

searched and cant find the diagram anyone got one?

 

if you cant find that then you don deserve to have a shiftlight...

either here on H-T or goto the Apex'i site and look for a VAFC manual... pin out is in there for most ecus.
