1996 ford bronco factory keyless entry?

so for door lock use pink / YELLOW C242 pin 4, door unlock pink/green C242 pin 5, horn dark blue C240 pin 26...all are negative trigger. for parking lights use brown C240 pin 24, door trigger BLACK/ light blue C242 pin 7 or 19...these are positive polarity.

Your all the freaken BEST! Im going to give it a shot this afternoon.... I do have a nice digital multi-meter as well, this is going to be fun with all your help. Thank you !!! MikeCloudCasters

Hi Mike,

To test for a (-) type wire like Lock or Unlock, set your DMM to 20V DC, connect the Red test lead to +12V constant ( battery ) and the Black test lead to the suspect wire.  DMM will indicate +12V when signal is present.

To test for a (+) type wire like Parking Lights, set your DMM to 20V DC and connect the Black test lead to chassis ground and the Red test lead to the suspect wire.  DMM will indicate +12V when signal is present.

Have fun with the DMM!  

Soldering is fun!

Here is what I think goes where with the help I have received. Please tell me if Im on the right track. so for door lock use pink / YELLOW C242 pin 4, (3 PIN - Green) door unlock pink/green C242 pin 5, (3 PIN - BLUE) horn dark blue C240 pin 26...all are negative trigger. (H2/8 - Brn/Blk) for parking lights use brown C240 pin 24, (H1/5 - White) door trigger BLACK/ light blue C242 pin 7 or 19...these are positive polarity. (H2/6 - Green) Am I right?? :) CloudCasters

Getting the power: I think I'm not wanting to grab the constant 12v from steering column. I think I will go the extra and grab dedicated 12v constant from the battery post and run it in through firewall (neatly and in a harness of course). I also was thinking of placing an inline fuse a couple inches from post connection? Good? What size fuse? Thanks All!!!CloudCasters

switch your door trigger to H2/12 (purple) as the bronco has positive triggered door switches. for H1/1 (red), use a 20 amp fuse on 14 gauge wire, the fuse is there to protect the wire. if you do do remote start functions, it is fine to use the wiring at the ignition switch/steering column.

All wires and testing instructions on how to confirm using a DMM have proven exact. Here are some photos for how its going.

I will spread the gaps on the factory wires a bit more (where the testing tap areas are) and then twist my wires into the spots, solder them then tape them.  After completed I will use black 3m wire loom and zip tie shut to hide the attachments.

I will do remote starter part tomorrow.  Also mounted siren in motor compartment area pointed down and where it will not get wet.
