Default Wiring a wireless door lock to existing system

Good evening guys.

I need advice from you electrical gurus out there. I have a 2003 Ranger 3.0 2 door long cab. This truck has electric door locks from the factory. I purchased a wireless door lock setup from Amazon. I am considering taking the lazy mans way out on this. I plan to mount the receiver some where under the dash and running the wires to the door lock switch in the drivers door and using the factory lock motors. My question is am I taking a chance on screwing up a computer or anything else by splicing into the switch wires?

I am new here and really enjoy the forum. You guys are a huge help!!

Many Thanks
The Boltman

I don't imagine that this will screw anything up. It's probably just a 12v signal to the motors, no feedback. If you are really concerned you can cut the connection back to the truck and just use your new signal.

But out of curiosity, if the lock motors are fine, why are you looking to splice in something new? What is stopping you from using the OEM equipment?

I would like to have a remote key fob to lock unlock the doors instead of having to use a key in the door.

Thanks for your reply!!!

Better off picking up the wires in the kick panel rather than chase wires through the door boot grommet and tab into the switch itself.

Pull the Drivers side kick panel, find the harness coming in from the door, roughly about 9" from the floor up and then look for the following wires.


| POWER LOCK|pink / YELLOW |- |driver door harness or PKP
| POWER UNLOCK|pink/lt. green *4 |- |driver door harness or PKP
| LOCK MOTOR|pink/black | |driver door harness
| UNLOCK MOTOR|RED / orange | |driver door harness

Thanks for all your input. I have tied into the 2 trigger wires from the drivers side switch and found a diagram to wire it using 2 relays. I ran out of time last week end, but plan to finish it up next weekend. You guys are great and I certainly appreciate your help!!

Why not buy an original Ford key FOB and be done with it? Maybe I like doing things the hard way......all the key FOBS I ever had were wireless....LOL
