I'm trying to fix the plugs on my Beltron. I found out which wire is which in the harness coming from the tester. The small 14-pin test plug has a lot of the wires either removed or cut off. If I could find out where the heater is and all the other connections on the pinout I can put it back together. I don't have any tubes handy with the small connector and couldn't look up one to find out what it is.
