I want to install a Performance Shift button on my 03 SSEi to take advantage of the performance shift functionality of the PCM. I have a DHP Powrtuner and can enable it accordingly.

My questions are:

1. Is it as simple as installing a toggle switch that grounds out Pin21 on the PCM?
2. Where on the firewall is the best place to run the wire through into the interior?

Thanks,
Tommy

1. A toggle switch is all you need. Mine is on pin21.


2. If you look at the firewall from the engine compartment, you should see a 3-4" black round rubber boot. I went straight through that and just continued to the center column. Then I just Dremeled a hole and mounted the switch.

I knew I saw someone on here with their'* hooked up...it was you! Thanks!
