Just finished wiring in the NEO AFC and got a CEL for the map sensor. I have the esm in there as well for the comptech SC, I hooked up the pressure input/output wires after the esm split and before the ecu. SO i have the map wire originaly being split by the esm, cut the side where it goes to the ecu, hooked the pressure signal to the esm wire and the other pressure signal to the ecu. So map to esm IN to ESM out to Pressure In to Pressure out to the ecu. I also cut the VTM and wired the ECU side to AFC. Any ideas? Thanks, Tom
