I am looking for the wire at the ecm connector that serves the exhaust bypass solenoid; I would like to install a switch to manually control the exhaust bypass valve, and would like to accomplish this in the passenger/driver compartment rather than at the right rear wheel where the solenoid is located; does anyone know the ecm connector position or wire color for this?

 

I installed a 3 way exhaust switch (Auto/stock - loud - quiet) on my DB9, write up with wiring locations etc, is below

yep paul, that's here I got the idea!; now I just have to identify my solenoid wire!!

 

I got a copy of the workshop manual and scrutinized for ecm pinouts but couldn't find the schematic i need.

 

does your db9 have 3 connectors to the ecm?; if so, which of the 3 was the white wire??; perhaps mine is similar enough that I can measure with a voltmeter while racing the engine.

 

The Vantage wiring is the same as the DB9, look for the connector in the front footwell with a white wire at Pin 19.

 

hi paul,
the central electronic module is located either in the passengers-side or drivers-side footwell of my 2010 amv8 vantage; can you instruct how to remove access panels to access? ... your db9 access is similar?
