I just installed a aftermarket alarm in my 99 Ltd and im having a hard time finding a wire to to tap into so that all the doors will trigger the alarm. I normaly just tap into the dirvers door pin switch but for some reason it only works the drivers door I then read somewhere to tap onto the key ring light and again it only does the drivers door. According to most wireing diagrams it says to go to the drivers side juction block, is it behind the fuse box, is it safe to use cause every other thread talks about having to replace it. Is there somewhere else i could tap into.
