I'm looking for some best practices for disconnecting electrical connectors on our 15+ year old cars. I've had to disconnect the coolant level sensor and the camshaft sensor in my 06 Coupe and found both of those electrical connectors to be total bears to get apart. In both cases I had to remove the sensor and use both hands to slowly wiggle the device loose from the connecting harness. The wiggling required several minutes and a bunch of worry I'd damage brittle plastic.
I have to do the crankshaft sensor next and I'm baffled how I'm going to get that beast disconnected with one hand. Any tips or tricks to deal with connectors that haven't been apart since the factory? Would some sort of spray lube further damage the old plastic? Thanks in advance
