2002 Magnum Wiring/Security ?
for simplicity, you would probably be better to use your truck gauges and starter relay, that way you would not be trying to use it through the computer system. as far as I know, a security enabled computer will start 3 or 4 times and die, then wont start. if yours is a security system, you'll have get the computer reflashed to get away from the security deal. mine is an 01 magnum and does not have security, so it may be possible to get an older computer from the u-pick yards, but good luck with that. there are places that will fix your comp. troubles, but cant give you any names. get ahold of player1up. I think he had his done. dave.
