I was revisiting this modification yesterday and noticed that this was done on a 3.4L engine. Since there are two ECT's on my 3.0 can someone tell me which ECT is used? The one on the drivers side of the engine or the rear of the engine near the firewall? Also any idea which wire would be the apropriate one to tap into?

Here this might help.

I wouldn't try to do that mod on a vehicle without OBDII, there is no way to check the tune on it, except trial and error. I don't like error with my engines, but that's just me.
