Subaru conversions are well known for problems with the blue wire for
the fridge relay or aux battery relay. The answer is to connect the blue
wire to X power on the relay panel instead of the original location.
Unplug the blue wire from G4 and move it to G3 or G1 instead. If both
have wires to them from other optional equipment one should have a short
dangling black/yellow stripe wire there to plug it into.
