First, thanks for edit my title.
I am in the mids of restoring a farm fresh 1978 T140E, the headlight assembly pitted and rusty. The connectors in the translucent terminations are sawer together, I have to cut the wire to disconnect them. The wires connected to the red around cylinder in the middle will not come out either, looks like I have to cut it also.
Like I've said, every connectors besides these three connectors are quick disconnect. What gives?
