Standard 2-wire door lock actuator (Universal)
Crutchfield Customer Review (What's this?)
This was not my usual DIY project! I installed these on a 1989 Toyota Xtra-Cab w/o power anything in the doors. This vehicle has wear on the door tumbler locks. My goal was to minimize further wear and provide relative cheap convenience. I have the Code Alarm CA1153 alarm which has built-in relays. I ordered the DA-1 (2 of them) from Crutchfield. Prior to shipment, I received a call from Crutchfield Technical Support to insure that I knew what I was doing and that I was aware that some alarms require external relays (2 per door) for these to function. That is support "before the sale"!!! I didn't need relays with my CA1153. Product arrived and boxes did not contain the instructions, as advertised. No problem...I had previously downloaded them from Crutchfield. Product was high quality (Crutchfield doesn't carry junk). I also had limited room to install the actuators. Not having to mount the external relays simplified my installation. These doors had never been opened up since the vehicle was built. While doing so, I cleaned the tumblers, locks, and window mechanism w/WD40. I then used air compressor to blow out excess WD40. Tumblers were lubricated with graphite. I then used white lithium grease to lubricate the lock and window mechanism. Since no power was in door, I had to drill (Step Drill) and install rubber wire looms which are available on web for under $5 each. I installed shrink tubing over wires to further protect them.
Pros: Convenience Quality product Works well Relays not required if alarm contains internal relays Thank you Crutchfield!
Cons: A lot of research and physical work to install on this particular vehicle, but definitely worth the trouble. Since this is a "Universal" product, the instructions are very generic. Use with different vehicles, different alarms, and different vehicle options make this a complex project. 2nd Unlock Option on CA1153 requires a single external relay to function.
