I bought a Proform adjustable RPM shift light that uses the existing tach. You just turn the dial to the point at which you want to shift and it lights up without the use of a big ugly tach.
It has a black wire, red wire and green wire. One is a ground, one goes to the tach terminal on an electric ignition and the other goes the ignition switch. What do I have to do to run all the wires and make this thing work. Do I have to mess with the ECU? Please anyone with any info or has installed a shift light before let me know, before I take it to someone that'll charge $200.

 

I bought a msd shift light ,but did"nt use ther light ,want to radio shack got led light mounted in pillar Tied into ECU

 

Spend the $65 and get the Helms manual. But yes, you will need to tap into the ECU signals.

 

Ok, so can anyone tell me where the ECU is located? Is it right beside the main fuse box under the hood? And also, where the electronic ignition is located ( i need to run a wire to the tach terminal) THanks!!!!!

 

It's behind the radio on the passenger side. JUst pull the carpeting aside on the passenger footwell. YOu'll see all the wires there.

 

 

Hey thanks alot Scalbert for taking the time to snap a shot. I appreciate it. I can't believe that nowhere in the owners manual does it tell you where the ECU is! Is the ignition easy to get too?

 

I'm guesing that you will tap one off the ingnition coil triggers. If so then refer to page 11-20; ECU connector B (24P). On terminal 10 (Yel/Grn) is the output for no. 1 ignition coil.

 

Ok thanks--I'm going to buy the manual. The instructions for this thing say if I wire to the ignition coil, the warranty will be void. I'll figure it out somehow.

 

when i had to tap into the ecu for the air-fuel ratio it was on the passenger side so it might be on that side.

 

just found out Helms doesn't make a manual for the 2003 CL yet! Now how do i type that damn mad face again......

 

They've been making it for almost a year now. See this thread.
