The 850 cockpit is a work of art

Wish I could figure out how to add the door lock switch, I have one dash spot left (no antenna switch). LOL

Have you got the door lock switch for the dash as adding it to the cars electrics is quite easy:

0V or chassis connects to the common of the switch
Lock position connects to Yellow/ Green wire going to the central locking relay pin 9A
Unlock position connects to Blue/ Pink wire going to the central locking relay pin 7B

Hope this helps, if you don't know which relay is the central locking relay just ask - Mike
