I'm having issues getting the power locks working on a 2000 Ford E350 my family just purchased. Pressing the lock and unlock buttons didn't work, and I later found the lock module behind a panel behind the drivers side. The module is toast. I attempted to solder new relays onto it with no luck, and its a discontinued part, so I've just unplugged it. It doesn't have keyless, just power locks. I have tracked down the following wires from testing switches / actuators, so I'm hoping someone can help me wire up a couple new relays to control the locks and bypass the old lock module. Everything I've found can be traced to the kick panel on either side.
Red Wire: 12+ when "Lock" is pressed (Seems to float at 6V when nothing is pressed from driver side but reads 0 when floating from passenger switch)
Brown Wire: 12+ when "Unlock" is pressed (Seems to float at 6V when nothing is pressed from driver side but reads 0 when floating from passenger switch)
Black and Green Wire: 12V from lock fuse (I've blown it a few times to prove that theory)
Pink and Black Wire: One of the two wires on lock actuators (originally reads 12V when lock or unlock is pressed at the old lock module plug)
Pink and Orange Wire: One of the two wires on lock actuators (originally reads 12V when lock or unlock is pressed at the old lock module plug)
I think this is a reverse polarity setup, but i'm just not able to figure out how to wire this up. Not sure if I need to cut any wires to make it happen.
On a side note, i'd like to add remote start to this rig soon too, so ideally i'd fix this in a way that makes both the buttons work, and allow me to add remote start later adding keyless ability. Any help is greatly appreciated!
