Here's a quick tutorial on how I modified Burger Motor Sports N54 Patch adapter for my EWG N55.
I'm using this setup for PI, but the same connections can be used for Meth or other fueling controllers. I chose to use the manifold MAP sensor for my PI for actual manifold pressure, and to avoid false boost spikes due to throttle closure.
The yellow wires on the TMAP/MAP on the chargepipe or intake manifold are the positive signal wire (Vin1 on AIC2-V/P).
The signal ground wire on the charepipe is the black and yellow wire on the opposite end of the connector.
The singal ground wire on the intake manitold MAP is the black and blue wire at the opposite end of the connector.
I purchased the following patch adapters from BMS and modified them via the video attached to allow a correct fit to my EWG harness

The patch adapters need to be trimmed for length, and repinned from 1234 to 4321 (flip them 180 degrees) for EWG. The wires should be a straight pass through as the OEM connectors are a direct fit. The patch adapter is only being used to tap into the wires, so the oem harness doesn't have to be mangled.
