1998 mustang alarm and radio problem
Hello, i have a 1998 3.8 v6 mustang with a cassette and separate cd player in dash. i recently removed the cassette player and spliced in an aftermarket head unit. the original cassette/radio had 4 plug in the back but i only used 2 of them: power, remote start, etc.. and the 4 speakers plug.
My problem is now my alarm does not work. I have no keyless entry, no trunk opening, or panic button. i thought the other 2, unused, plugs where just for the cd player, but now im thinking they powered the alarm too.
Any help would be much appreciated since my keys only start my car. they don't open the doors so i rely on my keyless entry a lot. thank you!
