Ive read a tonne of similar posts for answers but I have a problem..

I bought a right Click keyless entry system! Its got power, negative and earth (polo 06 facelift 9N by the way)

It's currently installed in the drivers door. A plug attaching to a lock ad unlock button on the inside is what I tried to attach my lock and unlock to...the unlock worked but only if I was inside the car! And the lock didn't work at all! Should I have installed this I'm the drivers footwell using the same coloured wires or am I currently correct?

Ps I'm a girl and 100% New to the wiring of a car (even though I done a lot of circuitry in school a few years ago)

Any help is appreciated, really don't want to have to take the whole system out and leave it, spent a whole day trying to figure it out! Ad if anyone has the wire colour I should be using for lock/unlock that would be amazing!
