I have no idea how my door opener kit would interface with a competitor's product. The Zilla stuff is great and bulletproof, but having owned 6 DeLoreans over the last 15 years, I have personally not yet needed any of it. There are other less costly ways to achieve a similar level of safety and convenience. My kit is self contained - two 3-button remotes, receiver, 2 actuators, and linkage. Its just a pair of actuators (not heavy solenoids) that use existing wiring. It unlocks the doors and opens one or both doors. I use a standard keyless remote unit to power them, but you can also use most alarm systems as long as there are extra buttons or functions to use. But with an alarm you wouldn't need half of my kit. This isn't rocket science. Frankly, anyone who is at all handy can do this without using my or Grady's kit. Think "power door locks" only its "unlock and unlatch" instead of just unlock. For a long time I declined offering a kit because of the many variables - alarm systems, wiring, etc. - but due to demand have finally put them on my web site. Yes the wiring is the hardest part, but if "plug and play" is worth an extra $800, you know where to go. -- Darryl Tinnerstet Specialty Automotive (delorean-parts.com) McCleary, WA
