Hello Herb--

I have a new replacement cable---the old cable is completely removed--yes, the cable controls the ram air valve in front of heat exchanger that passes turbo air into the janitrol unit.

It is the "routing" of the cable from the heat control levers at the bottom of the copilot instrument panel--through the front bulkhead and through the engine compartment to the ram air "butterfly" valve---that I can find no info on.

I am confident Cessna had a specific (safe) way they installed this cable and I want to put the new cable in correctly.

Thanks for your reply.----Ray
