Unconnected Red/Black plug found near MAF - 91 SHO

[Bill Mc]

hi gang - I'm relatively new to SHOs. I found this random un-connected plug near the intake ('91 SHO). Any ideas what it is supposed to be connected to? It just has a black and red wire. Option my car doesn't have? Thanks! Two photos:

I believe that is an unused connector. Someone else will chime in to confirm.

Heavy gauge, maybe a block heater?

Cool, thanks guys. I was replacing the "hot air" cone filter air intake the previous owner had installed. I put it back to stock. I found this plug in the process.
