Hoping to catch the attention of the experts -

I'm contemplating converting a LWB 140 to Diesel. Will the rest of the CAN work without the engine module? I can get a 603 to run with the EDS module out of a 124 or 126. I wonder if that means giving up SRS, ABS, ASR/ASD, convenience module and anything else hooked up to the CAN.

I suppose I can transfer the whole deal from a 140 Diesel. Is that more work that faking a gasser CAN to work with a 603?

Thanks,
