Can someone tell me what the white fish tank looking thingy is behind the head bay in a 90 vert ?
I can't flush mount my head unit with rear RCA cables. It almost won't fit with just the Molex connectors.
I have an 89 FSM, and it dosn't mention a peep about this "box".
It looks like an A/C condensation tank (?!?).
I'd put up a picture, but it's too damn cold out there today.
Options:
1) Safe to cut out a square & glue in a sealed recessed box for clearance ?
2) Is there a VERY low profile 90 degree "L" adapter for RCA interface ?
3) **** off the whole project & go iPod with headphones.

TIA!

That's the heater core and vent box. You likely can't get away with cutting it.

I have seen pretty tight angle RCA cables and/or adapters. I'd go that route.
