Install Keyless
 

My Camry has central locking system, but I'm missing the keyless entry.
I purchased a kit and would like to install it (done that once successfully, on a different car).
This Camry having its controls on the driver's door, I figure I could place there my keyless entry receiver,
conveniently tapping its connections to the existing control unit, once I locate them.
A number of wires are going to/coming from that control unit. I will only need 4:
+12V(constant), Ground, Lock Pulse and Unlock Pulse.
Openning the control unit, I could see on the PC board some terminals which seem waiting for such addition (suggestive markings).
I also unplugged the connector and using my multimeter, searched for the +12V(constant), but could not find it.
Is it because of the unplugged connector?
It would be of great help if I knew the color coding of all those wires.
Thanks for your attention.

I think it should be indicated on the manual...not sure about the coding because I don't memorize it but its should be in the manual.
