Hmm, interesting. I only see one white/blue wire on diagram. Others are white/green and white/black. There
is blue/white wire that goes to headlamp. That might be 2nd-wire on right.
Test for voltage on these:
- fuse box white wire, should have +12v full-time regardless of ignition-switch
- fuse box white/blue wire, should have +12v full-time
- fuse box white/black wire, should have +12v full-time
- white/blue wire at thermoswitch connector, still not sure about this one.
