Clutch and brake are straight off and new ones on jobs, just ensuring with needle nose pliers that the rubbers are pulled through into their grooves. You would see what I mean straight away.
Then the throttle has a bolt at the back and at the front there are 2 near invisible slots, I studied the new one to work out what I needed to do, I pushed a flat screwdriver in and manipulated and unpopped the clips. The electric plug on the throttle needs the grey part pushing down towards the socket on the pedal and it releases itself.
I put the new one in place, stood on it to pop it on the 2 posts, connected the plug and bolted the back.
Done.
