I have a nokia bluetooth that I would like to install but there is no fuse box inside the cab. I could pull the 12v constant and 12v switchable in from the fuse box but would rather just tie into something already inside. Were would be the best place to access these?

 

try the left power outlet its a non constant line the right power outlet is constant

 

I tapped in to the switched line for the 12v socket in the console beside the shifter. I use it for the GPS.
