Someone requested help on installing keyless door locks, I volunteered and bought a kit for my 1998 Ranger. The kit is essentially 2 kits packaged together. One kit is a door lock motor repeater which attaches mechanically to the threaded rod the door plunger is on. Pull up on the driver lock plunger and the passenger side pops up. Ditto press down and passenger side locks.
The other kit is a rf receiver with key fob transmitter but it isn't produced by the same company that makes the locks and the kits wouldn't marry without a relay interface. Interface papers were included but would not work with a Ranger type circuit.
Cost - $50 for kit(s) and $18 for Radio Shack relays. The distributor is hoffmangroup or autoloc.com. Got mine on eBay but they appear to be everywhere. Quality is fine except I would have preferred larger gauge wires since I cut everything to length, soldered and used heat shrink tubing. Soldering 26 ga wires is a pain.
Installation was straight forward except the relay wiring isn't for anyone without a soldering iron and experience using it. The relay and black boxes were placed under the steering wheel after I removed the existing defunct alarm module.
The hardest part was snaking wires through from door to cabin. Remove the speaker and break loose the accordion protective rubber thingy. Then working the wires through in 2 stages. First from door thru the rubber thingy then after removing the kick panel, into the cabin.
If anyone wonders how to take the doors apart see this thread:http://www.fordrangerforum.com/inter...-speakers.html
