Shift light install
 

Does anyone have an install how-to on installing an aftermarket shift-light? Ive installed them on single coil, MSD and other setups but haven't done it on a multi coil system like the Z has. Power and ground is easy, but not sure about where to tap into for the rpm signal.

Before people start flaming, my Z is a 7at supercharged and 1,2,into 3rd quick as hell to click through on the paddles, so a visual indicator is a nice benefit.

Thanks in advance.

Subd just for info. I wish we could set an audible alert like the STI guys

On other cars I have tapped into the rpm signal going into the Ecu , you can also get a signal off the back of the rev counter

For anyone looking to tap for RPM or a Tach. It's the first of the three harnesses off the ECU. It's the grey colored harness clip. Now due to the nature of this type of harness clip you can't count the pins to figure out. Which would be pin 14. I'm sure there's a way to undo the swing lock latch but I wasn't about to break it. Your looking for a red wire. There's three. A bigger one, one that's twisted around a white wire, and a smaller red wire by itself. The smaller one by itself is the one.

Bigger wire. Which also has a black sleeve on it to indentify.

Thanks, that should help out a lot.

The 7AT doesn't have the same one that the 6MT does? Adjustable RPM value in the trip computer.

Always something.

Always what SPOHN? It was a legit question.
