Patriot ECM locations

[Bob McCORMACK]

Need to do some welding in the battery compartment of my 96 Patriot.  Would like to disconnect the Cat. ECM just for safety but can't locate it.   Found the Allison controller up front.   Anyone know where the motor controller is located ?

I think that the engine control module (ECM) on your coach is bolted to  the engine block on the right side.

Thanks Gerald, confirmed from CAT Forum.  

 Now I just need to track down which fuses relate to the ECM so they can be disconnected as recommended by a CAT dealer.   Also recommended disconnecting both set of batteries (no brainer since I am rebuilding the whole battery box) and then hook positive & negative together for each set so there is no path.   In the case of the patriot that means both grounds from the house batteries.
