I'm going to install back my heater control panel, but i have two questions...

1. where is this yellow OBC cable for?

2. my car has a stock option automatic climate control. Where should i search the cable for the heater control. i guess it should come from the main heater, but i can't find it:

The other strange thing is that my temp control unit is normal, from a car without automatic heater control option. Maybe the main heater sometime in the years have been changed with a normal one without climate control option and that's why my control unit is normal and i can't find the wires for the heater control unit? The car is with aftermarket Davia A/C if it matters.

Thanks.

Yellow wire with plug isn't used on any OBC installation I've seen.

You mean something like the Webasto heaters or what?
