We are installing a new Thermo King Kv300 mobile unit to a truck this unit was purchased in China the problem I have is the wire numbers at the end of the harness do not match the terminals in the control box. The cable end numbers are C2,C1,E1,E2,PWR,PWR, the connectors in the control box are CFM2, CFM1, EFM1, EFM2, PWR R/G PWR R/W. Can you help in which cable end goes where. Thanks Ed.

Try to find the "secret" wiring diagram.  Almost all refrigerators have a hidden paper wiring diagram.  It is usually tucked into a slot under the refrig, behind the front grill, or otherwise on the inside of the lower rear cardboard fan cover, or sometimes inside the back area near the fan.  While you're in there, it's a good practice to clean the coils.

SOURCE: GE Profile SxS Refrigerator wont defrost after new heaters installed

The answer to your last question would be yes. You can test for voltage at the harness where you plugged in the new assembly. With the refrigerator defrost timer in the defrost mode do your voltage test. The thermo stat for the defrost does not close until the temperature drops to about 16°F. If you have and Ohm meter you can test for continuity through the heater assembly by testing heater end to end and bypassing the thermo disk. If you have voltage at the first point test where you connected the harness your timer is O.K.. If there is no voltage with timer in the defrost position it could be bad.

Wow! I am confused also. It sounds like it is more complicated than the ones I use. Can you send me an image of the relay and the terminals on the compressor?
I can tell you that the live wire ( wire with electricity) is the one that goes on the common terminal, that is the one that it at the top of the trangle formation, unless the formation is upside down then it goes on the bottom. Then the other neutral wire goes on the run terminal which is usually on the right if the triangle formation is right side up. Usually the neutral wire is white. So
try putting the white wire on terminal 3 and the orange on the top (or bottom) terminal. If there are any wires left over that you think need to be connected I would need to see an image.
