There’s a triangular retainer that clips over the peg on the edge connector, ease that away & wiggle the edge connector off the board.
I suspect a cheaper, nastier method of creating a fitting could have been found further down the barrel, but the bean counters at MG Rover didn’t have arms long enough to find anything worse further down.
I have a tube of Electrolube which was costly when I got the stuff many years ago & prior to reassembly I wipe a small amount on to the edge contacts, this, I feel extends the reliability between visits.
The “wires” to the bulb holders & the bulb peg retainers within the holders are tin coated steel, the bottom contact is some brass alloy, also tin flashed.
These crap choices are the roots of intermittentsy problems within the assemblies.
