Thanks Smitty, we are starting the 2nd car now, this is the last car in the chain. the first car to mod was the 2nd to last, we have not had any communication problems that i know of. I have made a note and put it in my epoch file, we are going to mod another 4 car group in the future. the mod we are on now is a 5 car group, the first 4 cars are on one comm loop, and the 5th is by itself, i figured that much out, then i just tucked the comm loop wiring in the gutter, and kept the eq and fire service wires together, and let the mod crew tear the controller out. have not had any problems yet,
maybe strange things are happening there and I'm not being told, i will check it out thanks again smitty.
