Then rewire the proximity wire in the handle with a 12 volt pigtail that'll plug in to the connector now under the hatch. Then on the EVSE side connect the proximity wire to another pigtail that I can plug my 12 volt charger into. Then I can charge the 12 volt battery by simply connecting the pigtail on the handle and hatch when I'm plugging in to charge.
What do you all think?
Not too sure if I get the "jist" of what you are asking - but off the top, some things to check;
1. Is the proximity wiring capable of handling the current of your charger? (could be OK with a trickle type)
2. Is there a common DC (12 volt system) ground already established to complete the circuit since you have only one of the two wires required for a DC circuit? I have an OE also, but don't recall if the J1772 established a common ground with the 12 volt system - or if you'd want to use it if so since it may be used for "signalling" with voltage spikes potentially interfering.
Bottom line, if these is some way to do this with the OE supplied plug/wiring (I too have the extra wire), I'd be interested.
