2006 5.3
Ok seems like that was a dumb question. sorry
I have a Fast EFI fuel sys and a MSD ign sys and both have a ect plug I also have a manual gage in the car. my problem now is that I can only find 2 places to have sending units, one in each head. any ideas where I can read the third ECT from?
my motor is 2006 5.3

I tried to start the motor today but no spark.
I am lost now.
