Ok, this is right out of the manual, correct? (pg 13A-135 and 13A-136)
That means that EGRT Ground is called pin #1; EGRT signal is called pin #2
I know this will sound dumb, but do I connect the EGRT ground to the MAP sensor ground, and the EGRT signal to the MAP sensor signal? The ground to ground sounds right, but it sounds odd that you would send a signal from the MAP sensor to something that already has a voltage output (i.e. pin #2 which is already reading ~4.5V). It seems like that wouldn't work. If I hook it up the other way, then the EGRT signal goes to ground on the MAP sensor, and the MAP sensor signal gets sent to ground, or is that the place where the ECU is looking for the modified EGRT signal?
