Hi all,
I've asked this question before recently and didn't get an answer

Can somebody please tell me what the 3 wires in the central locking are for

They are black. blue . Green & white.

I want to wire up a remote central locking kit and don't own a multimeter.I have found out not to waste money on a flip out key as they don't do one for the bongo,even if the one supplied look the same and have the same reference no. as the original

Many thanks Dave
