The issue is more likely to be in the bayonet fitting you put the lamp into than in the wiring on the harness plate.
Not being funny here, but you clearly don't know what you're doing, so don't fuck with it. Get it wrong and you'll melt shit or seriously hurt yourself.
Go online and find an NICEIC registered electrician near you and ask them to come fix it for you
