Sweet! Thanks for the link, that will give me something to do this weekend. On the realy, did you just use pin #47 for the ground on the realy? And are other year models the same as in the pin # on the pcm? Also im not sure if your vid is working or not, Everytime Ive tried to watch it I end up at the photobucket home page.

How is the lag when shifting WOT at 6200 rpm? I'd like to see a log with this circuit connected to a HP Tuners MPVI harness (or equivalent) against the RPM PID and see how accurate it is...

I did this yesterday finally and the Red connector Pin 47 did have a wire in it. It was yellow I believe. I got everything made and wired up but the LEDs have a real dim glow to them when they arent on. Guess Ill have to try a relay and see if they helps.

One last question, Is this possible on a 98? I went to do this mod to a buds 98 trans am and first thing I noticed was the hpt file didnt have the option to activate the shift light, 2nd thing I noticed was the PCM was wired differently. Is it possible to load a new .hpt from a 99 or etc and if so which pin on the PCM will be used?
Thanks!
