[TMC] More info on GPR-90 Relay Connector

[John Poulton]

Dave McDonald asked me to forward this info to the group.  It's yet another
Cinch part number for the polarized 2-pin connector that mates with the
"Relay" connector on the back of the GPR-90.

Unfortunately, the new info (Cinch p/n 2744 or ST-152) didn't yield any
immediate hits on google.... sigh.  It really is amazing how this
once-very-common connector has completely disappeared from our universe!
