Is there any chance you would know what wire is the "always live feed" to the PCM , or where it's fed from on a 03 Dakota 3.9l ? I started with replacing the fuel pump then checked all the sensors then replaced the PCM just to find out it's supposed to have a hot wire, and well it doesn't so I believe that it's shorted out but idk witch one it is or well witch one feeds it I found a wire that jumps 1-12v but I'm not sure if I could just run a jumper wire, I don't want to burn up a new PCM ... Could you please help
