Can anyone shed light, please? I'm fishing wires around the rear end of my 2002 RAV for a trailer hookup, and I discover a curious lump - plastic, roughly cubical, blue/green, about 1.5"x1.5"x1" loosely (but securely) attached to the interior body metalwork inside the top, left corner of the triangular aperture which gives access to the left, rear light cluster (ie: to the side-corner of the body beside the rear-door hinges.
Inspection-mirror + light shows some wires going to the rear side of the lump, and there *may* be a detachable cover at the front which might reveal pins. Could it be a trailer-hookup connector? That would be nice...
Or, what is it? Can't (yet) detach it, and its wires seem short, so it might not gain me much, visibility-wise. The wires seem to enter the rear wiring-harness, however.
TIA for any clues! Geoff.
