Fron what I found from Full Throttle, GNType.org, Pacemaker, & "jsta6":

The OEM stock MAP sensor on the passenger side fender gets its power (5V) from the OEM instrument cluster.

Feeding the sensor is a grey wire with a known not-so-reliable 5V power source. To make it reliable, you can get power from the ECM. The blue wire comming out of the ECM port C13 has 5V for the TPS. Go to connector C437, PIN B, and cut the grey wire that goes to the MAP sensor and connect it to the blue wire coming out of the ECM port C13.

The OEM stock MAP sensor sends the boost signal out on the green wire from the MAP sensor. This wire goes back to the OEM instrument cluster.

To re-route the OEM MAP sensor signal to PL, go to connector C437, PIN A, and cut the green wire that goes to the MAP sensor and connect it to input 2 of the Power Logger analog connection unit.

Start the power logger program and change the map setting to 2 bar.

My question is if I want to keep the OEM boost gauge on the I/P still functional, and feed the PL, can I just tap/splice into the green wire coming out of connector C437, Pin A or will this cause issues? Voltage should be the same but not sure if PL uses current for reference or just voltage?

Thanks.
