This connector is stock run through the taillight wiring loom but I’m not sure what its for. Can anyone tell me what its for. I have a 1991 Acura DA9 all American lol. Just hella curious about this haha.
If its has 8 cavities (edit) and on the left (driver side) its for connecting trailer lighting.
If I recall it’s the pigtail for a taillight harness if you were to install a tow hitch… As odd as that sounds.

Damn you TegFan!
48 seconds too slow! 
Haha that’s what I thought it was… Just was t for sure in that
yup, i just removed my trailer hitch but the wiring is still plugged up lol
I think its 6pin. Not sure but thanks guys. Makes sense.
Yeah my bad. In the service manual is says 8 cavitiy.
or its the plug that allows you to hook up your awesome nitrous bottle warmer. jk.
