interior wiring help
 

working on the interior of my 1987 TII, I bought it as a roller and the interior was all apart so i'm trying to put the puzzle back together. Can anyone tell me what the plug pictured is for? I think i have the other end but its been cut. located behind the glove-box where the interior harnesses connect.

looks like some sort of voltage regulator box

Looks like a heater vent...

Could you get a slightly better picture of the part number on the part in question? I'm having trouble determining the last two characters. All I can read is FB01-67-7xx. I believe the second to last character is a 3, but I'm not entirely sure. If you can get that information, I'll check in the parts catalog and get you a pinout for it too.

Since it's a TII, it wouldn't logically be the 4AT Control Unit despite being in close proximity to where it would go in an automatic car. Anything convertible-specific would have a FB67 prefix while GXL-specific is FB07/FB08, so that rules out audio amps. TII-specific parts begin with FB44

it's anti theft.
and the big black box is a speaker amp.
