my father has an allegro bus with a freightliner chassis and cummins, 2000 model. he is planning on buying a comp box from edge i think. he needs a pyro but the rv is a diesel pusher (rear mounted engine).

anyone know if i can get a pyro with an extra long set of wires to run all the way to the front of a 36-40ft. rv

also, anyone know of any other boxes. i was told it is a b-series cummins with 275hp.

HTH This is where I got mine.

 

If you match the type, material and size of the wire, I think you would be able to splice your own extension from the guage to the probe. The thermocouple wires to the outboard engines on our aircraft run an extensive distance between guage and coupler (down fuselage, around wing root, down wing and then down the pylon to the turbine section. Could be 50-70 feet of wire there..
