Connector under driver's seat

[Cox Abele]

I am swapping my manual for an automatic and will need to swap harnesses to enable TCU shifting. I have pulled the harness from my once automatic parts car and have looked over the connectors, finding the harness to be nearly identical except for the following connector.

What is this one for? It sits under the driver's seat and is part of the rear o2 branch of the engine harness. It has 5 wires and travels back into another harness running along the driver's side door sill. This is in the 5-speed harness of a 1998 Spyder.

could be taillights or for the rear windshield wiper if you have one

You have got to be kidding me, right?

The wire colors make me think it's for the fuel sending unit.

whats up man, I hope we can figure out what that plug is for. I was thinking about taking my seat off again, and checking it out, but my car is a 95 manual, not sure how different.
Thing is, I was down there for a while slowly messing with all the wires under the seat, to get the rear 02 unpluged (replaced) and the drivers seat wire had to be repaired. I really don't remember that plug at all, but would you think it would help for me to check anyways?

does the car in the picture have a keyless entry module built in the drivers side wall behind the plastic? only thing i can think of besides the 2 different fuel sending units.

I believe Colt4G63 also is correct, maybe this will help:

For the '98+ (possibly '97?) 4G63 vehicles:

Pin 1 - Red, for EVAP emission ventilation solenoid, power
Pin 2 - Blue w/ red, for EVAP emission ventilation solenoid, to ECU pin 55
Pin 3 - Don't find it anywhere so I assume none

Pins 4, 5, and 6 are for the fuel tank differential pressure sensor.
Pin 4 - Green w/ yellow
Pin 5 - Blue w/ white, to ECU pin 61
Pin 6 - Black, ground
