Where should this Tan/White Wire Connect?

[SJSbackyard]

Recently purchased 1987 3500 High Sierra, 350cid, w/TBI. Just forward of the TBI, there's a tan/white wire that is not connected. I'm hoping someone can identify where, in the fuel related system, it should be connected. I have attempted to attach a photo showing the wire (colored arrow).

The issue I'm working on is to solve a cold start problem...

If no one answers I'll try to look tonight or tomorrow.

Thank-you.

I tested and found continuity between the tan/white wire forward of the TBI, and the fuel pump relay (firewall). They're certainly within the same circuit. I next checked for voltage...none...appears as a ground. I really don't like to have a stray wire left, as I'm currently installing two fuel tanks and pumps.

Circuit 551, Tan/Wht:  ECM ground connected to intake manifold stud adjacent to thermostat housing.  See the 1987 Wiring Manual, grid Q43.

Another loose-end taken care of...
