We have a JD 4840 with an old Panisonic AM radio and we want to put in a Pioneer DEH-P6500 cd player. The problem I'm running into is I the wiring harness on the tractor has power, ground, left and right speakers pos and neg. and the harness from the pioneer has a 12v constant hot, 12v ignition/switch, and illumination wires. I want to know if I can just wire 12v ignition and illumination together and then to the hot from the tractor?
How to install aftermarket stereo into John Deere 4840?
