[aprssig] 12V wiring ideas

Are you sure that because of the extreme conditions you describe you haven't 
taken steps to make sure that none of the connectors are stressed (because 
of care you took when installing all cables?)   I have trouble simply 
keeping an Elecraft transverter connected---any movement results in 
"connector failure."
