sorry guys, i dunno if i should've kept the old thread or not but i got another question.

i found this esm wiring configuration:

Comptech ESM Red Wire (Power) -> ECU Pin 19 Yel/Red Wire
Comptech ESM Black Wire (GND) -> ECU Pin 7 Grn/Wht Wire

Comptech ESM Green Wire (Signal) -> ECU Pin 17 Grn/Red Wire
Comptech ESM Blue Wire (Signal) -> To MAP Sensor Grn/Red Wire

but that didn't specify to cut the map sensor wire. after i found another diagram:

in the second diagram, it said to cut the map sensor wire, is that necessary? and why? and also does it matter which wire is on which end (ecu-->green-->ecu-->blue-->map sensor)?

much appreciated, Thanks!

 

In the bold, you are essentially saying the same thing. Make sure to CUT the wire. You are intercepting the signal so the ECU doesn't see BOOST pressure signals. YES, the order matters. Green -> ECU side and Blue -> Map side.

 

oh...ok. Thanks for your help!

 

Hey I'm lost in this esm sorcery. Does it save me the hassle of needing an aem ems or hontata's ecu??
