Hi, I am a newbie but relatively proficient at installing my own stuff. I have no problems with stereos. Now I want to install an alarm in my 1990 full sized Ford Bronco. I have installed an alarm once before with no problems, but this one has remote start and keyless entry. I have never done either. It is one of the ones with the LCD pager remote. I have printed out all of the generic information here at the12volt.com. But does anybody have any advice specific to my Bronco that would be helpful? ESPECIALLY - what type of door lock scheme I have and the best way to hook up the keyless entry (it already has power locks)? Also any advice specific to the remote start? I could also use any diagrams that would be helpful. If some of the pros here could help me, I would sure appreciate it. I can't afford the $200 that they want to install it. If you want to send me any documents, you can send them to 1Ringo! at gmail.com I sure appreciate it!

I saw this on one of the replies - "Immobilizer Bypass Module: Required: No Type: N/A Part #: N/A " What is this? Do I actually need this? Is it part of the kit? Is there anything else that I need that may not be in the kit?

Your model year does not have any sort of alarm system. That is what it means.

OK so I do not need one, correct? Thanks again everybody. I'll bet that you are glad that you are not in my shoes! But I will get it done. It might take ten times longer than it takes you guys, but I will get it done, and then I will be pretty good at installing by the time I finish it. One more question - I see the diagrams for illuminated entry. Does my alarm need to specify "illuminated entry" or can I make it work with a relay or something? I'd like to have illuminated entry. ------------- 1990 Ford Bronco XLT Alpine/Kenwood XM system 2 amps 5 speakers Keyless entry remote start soon to have DVD player
