I have a Harlan Engineering shift light (http://www.harlan-engineering.com/store/store.html)
I tried to install it today and found out i dont know what im doing. Here is my problem I have a coil on plug ignition (04 mustang) this light is designed to work with COPI I tried hooking the signal wire to the #1 coil (tried both wires) and I get nothing. the light is set up fine its just not getting the signal, does anybody know were to get the tach signal
 
hmm, its supposed to be the green wire to the negative on the coil... does it at least light up when the ignition is turned on?
 
I wanna say it's something with setting for a 4 cylinder or v6 car instead of the 8 cylinder but can't remember exactly
 
If you are using your shift light in an LS1 F or Y body vehicle you will need to set the dip switches for the number of cylinders of the car, e.g. your number of cylinders is eight, look at the dip switch settings for eight cylinders and it shows ON dip switch 2 (see also Chart 1), Off Dip switches 1, 3-7. In this case you need to turn "on" DIP switch number two (2) and turn the rest of them down. Once you have the correct DIP switch setting press and hold down push button number one (1) for approximately 2 seconds (until it starts flashing repeatedly). Once the light starts to flash repeatedly, let go of push button number one (1). The light should flash back four (4) times to signify that you have the correct setting.

Chart 1

Dip Switch 1 2
3 4 5 6 7
# Cylinders
6 Off Off On Off Off Off Off
8 Off On Off Off Off Off Off

You will then need to program the rpm you want the shift light to activate on. This is done using the "rpm" chart Harlan inserts in the install instructions (see also Chart 2). You can program the rpm setting you want in 100 rpm increments. We chose to program our shift light to 5800 rpm's. That seems to work the best with out factory 6200 rpm rev limit. I will post part of the chart from 5800 rpm's to 7000 rpm's. When you decide on the rpm to set your shift light to, you will need to reset the appropriate switches to the new position. Once you get the switches to the new position, press and hold down Push Button #2 on the board. The light should flash back the first two numbers of the rpm setting you have programmed in. In our case the light flashed five (5) times, then paused, then flashed eight (8) more times. That represents 5800 rpm's.

You should have bought the one I have in my car.....it was very easy to install and setting it was even easier because the buttons are right on the top of it. I hope that little chart I posted helps you out.
