Okay, I'm using the OEM AC/ Heater control panel with cables. The instructions call for a control wire to go from the panel into the engine bay and connect to a heater control valve which is connected to one of the heater hoses.

I have a bulk head fitting on the firewall. So, there is a short length of heater hose that goes from the under dash AC/heater unit to the bulk head fitting.

So here is my question, instead of running the cable through the firewall. Can I move the heater control valve to the short length of hose under the dash?

I plan on calling Vintage Air on Monday, because it was too late to call them today.
