Since I use my RRC as a daily driver racking up ~300 miles a week, I decided to do some creature comfort upgrades to make the time more pleasant. Not that keenly watching gauges and listening for new noises of repairs-to-come isn?t engaging, but I needed the occasional distraction from the constant needs of the truck.
First the stock stereo had to go. I mostly listen to XM or iPod and the cassette adapter and stock speakers just didn?t cut it, ignoring the fact that the ADS sub had long ago disintegrated. I pulled out the stock bits front and back and replaced it with an Alpine head unit that has separate iPod controls and an AUX in for the XM receiver. I mounted a 6.5? Bazooka in the rear in place of the stock sub/amp/changer. Lastly, I installed Infinity 5? component speakers in the stock front door location and 6.5? coaxial in the rear doors. The new setup sounds awesome, and aside from the ugly Infinity grills it doesn?t feel out of place in the truck.
Alongside the stereo upgrade I wanted keyless entry. Yes, I could find the stock rover handsets and go through the programming routine, but where?s the challenge in that? Instead, I bought a $50 Audiovox AA-925 keyless entry system and retrofit it into the existing central locking. First thing I had to do was fix the binding of the locks in the driver and passenger doors to keep them from doing the up/down/up/down dance whenever I locked or unlocked the doors. The motors have a switch that tells the control unit to lock or unlock and my locks were pushing themselves up when I?d lock them and the system would go haywire trying to correct itself.
Once that was done, I wired the system along with the stereo for power/ignition etc. I ignored the door pin switch, interior light, horn, and other nonsense since I only wanted remote locking/unlocking. However, I did tap into the red wire coming from the light switch to get the parking lights to flash.
Tapping into the central locking unit was a bit more challenging. The AA-925 has two wires to control the locks, one is for lock and the other is for unlock. When locking, the unit sends a ground pulse then positive pulse down one wire and the opposite down the other wire. Since the Rover needs a ground pulse to lock and unlock, and as I learned doesn?t react well to a positive pulse, I ended up putting in two relays, one for lock and one for unlock, that used the 925?s positive pulse to send a ground pulse to the rover control module. In this setup I ended up with the following:
With this setup the Audiovox remotes lock and unlock all doors and it only cost $50. Plus, there are additional channels if I wanted to add a starter, open the gas filler door, etc.
Sorry for the long winded post, but I hadn?t seen anyone write this up before and wanted to contribute. Attached are pics of my installation and a wiring diagram of the RRC lock control unit.

Unlock:
925 Red to Relay(85)
Relay switched output(87) to yellow/orange wire on Rover harness

Relay pins 86 and 30 are grounded
