Electrical Receptacle

[Garagerat]

This receptacle is on an 06 Night Train. It is located by the battery. What connects into it?

TSSM if I had to guess with only that pic.

It was the TSSM. Thanks.
I going to make another post about an additional receptacle I cannot locate.

I really appreciate the help everyone on this forum provides.

Here is an additional receptacle that I would like identified on an 06 Night Train. It is near the TSSM.You cannot view this attachment.

You can use the wiring diagram and the colors of the wires to ID them. A triangular plug with R/W, Bk, & W/G could be the plug for the vehicle speed sensor ( which reads off of the transmission).

Yes it's the VSS. But in the future, just find what fits it. Or do what @rigidthumper said.

Thank you both for identifying the part.
