    I sent a PM to arveetek asking him what the bare essentials were for wiring on a 6.2 so that when I get the Toy ready, I would know. After reading his respone, I (with expressed permission /forums/images/graemlins/deal.gif) figures that it wouldn't hurt to post it for others to see. So here it is: [ QUOTE ]
    The starter and alternator wiring is needed, and you need at least one wire going to the injection pump...this is the fuel cut-off solenoid. You want to send 12 volts positive from the ignition to this wire on top of the pump to keep the engine running...removing power shuts the engine off.

    There is also another wire going to the pump that advances the timing when the enging is cold, but you don't really NEED that wire to get the engine started, but it does help. This wire runs off a temperature switch, or you could wire it up manually to a switch on the dash. Again, if you want the bare minimum, don't worry about this one. Same goes for the high idle solenoid and wire.

    You have to have glow plugs in the heads in order to seal up the combustion chambers, so you might as well wire them up. Most 6.2L diesels won't start without them even on a 60 degree day anyway. Just wire up all the plugs together, and then mount a Ford style starter solenoid on the firewall. Put the plugs on one side of the solenoid, and battery power on the other. Then hook up a momentary switch inside the cab to engergize the solenoid. Hold the glow plugs on for about 10 seconds and then let go and start it.

    So, here's the list of wires you MUST HAVE:

    Fuel cut-off wire on injection pump

    Wires that are HIGHLY RECOMMENDED:

    Glow plugs

    Wires that are nice, but not totally necessary:

    High idle
    Cold timing advance

    That's about it, I think!
