Chassis Plug Identification - interior near ECU
 

Ok, I moved and extended the harness plugs that enter from the passenger side wheel well into the engine bay. This includes ASCD stuff, some big plug, and whatnot. The car is an automatic, and I can't find where this last plug goes into. I've checked all extensions of the main harness around the site, and im fairly certain it plugged in somewhere.

If anyone has any insight or can check their car for me, let me know. Thanks

Edit
a little more information, its part of the chassis harness not the engine harness, the one that controls headlights and whatnot, extends around engine bay etc.

Come on Ahmad
It's the plug from the ECU harness to the ATC. Not needed since the car is no longer auto.

Did you miss the statement saying that the car is automatic? Furthermore the ATC connector is much longer than the one in the picture and it has a bolt that screws into the transmission control unit.

Anyway....After looking at the FSM for the 89-90 and 91-94 S13 the best thing I could come up with is to tell you to check underneath the dash for the male plug hanging down off of the interior harness just above the ECU.
