Electric Water Pump Ignition Signal I'm putting an LS3 that has an electric Meziere water pump into my 1998 Trans Am (has a 2002 ECU). I have the relay kit that goes with it, but I need an ignition signal wire to trigger the relay. For those of you with electric water pumps or other items that you wish to run only when the car is running, which underhood wire have you tapped (color is also helpful)? Thanks in advance for suggestions.

I used the gray wire that also triggers the fuel pump
