Possibly but not likely. Games all have the wiring color coded so you can "easily" trace from one end to another. I say "easily" because sometimes it's still tedious but I don't see how a seeker would help.

However some games do not have colored wiring, or it's faded, damaged, hacked maybe. In these cases I could see it being potentially useful.

I have a Sperry Wire Tracker that I have had limited success with. On EMs, parallel circuits make it difficult to use. I found it was easier to open the loom and hand over fist trace a wire(if they weren’t color coded).

Trying to figure out wiring colors when they're so faded and discolored is certainly not my favorite thing to do. If there was a tool that could help make wiring easier to trace in that situation, that would be awesome.

Yeah, I don't think this tool is intended to be used in situations where wiring is tightly packed together like on a pin. It seems to be more designed for helping with wiring that has more separation, like electrical or network cabling in walls.
