Ok i'm about to lose my mind here. I just installed a magicar 8100 alarm/remote starter. I have everything working great except for the power locks. Apparently Bronc's have 5 wire reverse polarity power locks, and this requires the use of two relays in order to make them work with the alarm. I have been trying for days to get the things to work with no success. If anyone has installed any alarm that required using the relays to control the lock recently please help me out! Any pictures descriptions diagrams or advise is GREATLY sought.

 

It's a Ford thing.... you will need to get an additional module to incorporate into the system. Yes they use a polarity switching system. If one is not available you have 2 choices... retain your original keyless entry and carry 2 fobs on your key ring or see if the alarm manufacturer has the module.... if not change alarm brands.

 

I figured out what i was missing. Didn't have a good ground on the relays to activate them. I've got a 93 so no factory keyless, but thanks for the reply. When i get done with it i might post a diagram so anyone else that needs this info can get it.

 

Cool post it.
Which brand did you go with ?
I wonder which to buy,I installed a
$50 cheapie in my 90.
Like to get a better one for my 96.
