Default 87' Base C4 Factory engine harness wire question

In the process of restoring a C4 - which needed a new engine harness amongst many other items.

Bought a stock harness after looking for months. Showed up and looks great! I did find a few cut wires, close to the bulk head connector on the driver side. Black/White line, Green/White line, Orange, 2 Red.

I assume this was one connection - but I don't to what..... not having a reference point to start with, I'm lost in schematics from the FSM.

Any know off hand what these belong to?

Looks like the fuel pump relay. Page 8A-20-7 in the FSM.
