I do have spare larger gauge wires for the 12v input to battery positive and another as output to the glow plug bus bar (both red, R). There's also a ground (black, SB). I likely won't be able to get all of the same color wiring as factory. I suppose I could go to a few junkyards to find similar wiring colors, if I really wanted to.
My question is: can I de-pin the wires in the 4-pin glow plug relay connector, so that I can re-use the connector? I don't have the connector here to examine it myself.

Not as elegant as Tom B.'s solution but so far it is functional.

Actually IMHO Tom's solution is more work than one really would need to do. I guess the benefit of his method is preserving original wire colors. But I am assuming in your case the concern is less about the integrity of those round terminals and more about the wire insulation falling off (at least that's always been the issue with my cars....
).
The 4-way connector can easily be de-pinned (connector body comes apart like lego as Tom's post shows) and my solution has been to just use junkyard harness parts to salvage new female pins with several inches of wire pigtail of whatever color I can find, not caring too much about that since you still have wire position as a reference for troubleshooting if it's ever needed. Make a good splice back down where it meets the main harness, install the new pins in the connector, and it's good to go.
Or ngoma's suggested method of using the existing pins and short pigtails and just replacing most of the wire. Similar outcome and probably even more efficient in terms of effort vs result.
Some of us touch up with brushed-on "liquid electrical tape" for years as the insulation crumbles away but that's a game you can only take so far.
