68 C10 No heater wiring

[scottcorvette]

Getting to the end of my UK based ratty C10 project. My heater was missing completely and its bloody cold over here all the time. So I sourced through US ebay a complete non a/c heater box and controls, and from ECE a new heater core, control resistor, hoses, and control reface kit. All nicely installed and ready to hook up. Lo and behold no heater wiring of any sort.

Does anybody have a good diagram of what wire should go where?

I am going to have to make up a heater harness. I think I have found the original feed wire which is a brown from the ignition switch, but it disappears under the carpet and has been cut off. I need to know what happens from there.....

Thanks in advance.
Scott, shivering in England!
