2007 kia rio, keyless entry

I am trying to install keyless entry onto the existing central locking on a KIA RIO 2007 . I have worked out that the locking unlocks with a negative feed to the blue/black wire, but cannot work out how it locks. When I unplug the wiring plug in the kick panel the doors lock, a negative feed will unlock the door but I cant find a wire that will relock the door. The wiring colours available in the drivers door are grey, blue/black,BROWN / orange, black. Can anyone help ? Thanks

Do you have a rocker switch at the door controls in the driver door?commit your way to jehovah and he will act in your behalf. psalms 37:5

Yes it has a rocker switch on both doors

Have you tested at the switch to see? test all the wires while using the rocker switch to activate the locks, record your readings and let me know! Most likely it should be negative trigger!commit your way to jehovah and he will act in your behalf. psalms 37:5

Thanks for your help. It may be a few days before I can get some spare time to have another look, but I will post my findings. cheers

     Power Unlock          YELLOW/BLACK          (-)          IN HARNESS IN DRIVER KICKPANEL                PowerLock          BLUE          (-)          IN HARNESS IN DRIVER KICKPANEL hmm you say negative to it unlocks it and unplugging the plug locks it? Try cutting the wire that unlocks with a negative and see if it locks... then report back.A DMM is a beautiful thing.

ive used those yellow/black and blue wires you can grab them in the kick or at the fuse box in a white plug at the top left of the box the 2 top pins 6 and 16If i Can't Install it    I Don't need it   Joe

Yes when the plug is unplugged it locks the doors then if you send a negative to the blue/black it unlocks. I will have another play about.

Thanks Guys . It was the BLACK/ blue wire managed to locate in the drivers kick panel, + lock, - unlock. thanks for your help
