Replaced thermostat, which looked like it had been in battle. I was trying to test the electrical, but can't for the life of me figure out how to disconnect the radiator fan connectors. I removed the red pin, but can't figure out where to press to pull it off. I've tried with a screwdriver and without but there's not a lot of room to get a good look at it. I don't want to break it but it's really frustrating
I found the tab. It was near the end closest to the wires. By squeezing it with pliars I was able to wiggle it off fairly easily. Once disconnected, it's obvious when you can get a good look at it. So onto the next feat.
