Quick question. I believe this wire in the photo is the feed for the glow plugs from the switch. The terminal is in need of replacement. How do I remove the "fitting" that holds it in place? It's not a nut or screw head. I assume it is treaded on to the post. I don't want to do something silly. I am following the tread for adding a selnoid to help with a cold starting problem on a universal diesel 5424 and this is the first step.

put a screwdriver in the slot and give it a twist to loosen it. My guess is this was done for hard to reach spaces where reaching the knurled nut it tough.
It looks like paint may be in the slot, but a thin screwdriver should fit.
