Sherman, I would use the heaviest gauge battery cables I could find, the smaller the gauge number the better. Leave both battery connctions OFF until you triple check everything. (1) Run the black cable from negative battery terminal to the torque tube or other ground. Make sure you clean to bare metal, no rust or paint. (2) Run a ten gauge wire from the screw post on the alternator to the plus side of the AMMETER. (This is only if you have an ammeter, sometimes a voltmeter is mistaken for an ammeter and they must be connected differently). (3) Run another ten gauge wire from the negative terminal of the ammeter to the battery terminal on the starter solenoid. (4) Run the RED battery cable from the positive post of the battery to the battery terminal on the starter solenoid. (5) Run a twelve gauge wire from the red wire in your alternator pigtail to the battery terminal on the starter solenoid. DO NOT JUST TIE THIS WIRE TO THE OUTPUT POST ON THE ALTERNATOR. It measures the voltage at the battery to compensate for losses in the wiring / connections. (6) Run a 10 gauge wire from the battery terminal of the starter solenid to the batt. terminal on your ignition switch. (7) Run a tweleve gauge wire from the IGN. terminal of your switch to the positive side of the coil. (8) Using the same gauge wire, connect the negative terminal of the coil to the distributer. (9) Connect another twelve gauge wire from the ign. terminal of your switch to the white wire in your pigtail. (10) Connect the start terminal of your ign. switch to the starter solinoid coil. (11) If your solinoid has a ground connection connect it to the chassis. (Some ground through the bracket.) (12) Connect your starter to the starter terminal on your solinoid. (13) Make sure your alternator has a good ground through the bracket you made. This should get you up and running. My pigtail had brown and red wires the brown is to the left and the red is to the right as viewed from the back (NOT THE FAN/PULLEY) end. As the fuse only protects the light wiring, use gromets, tape, and protective tubing to protect this wire from abrasions and cuts. Make sure all you crimps are tight and you don't cut any strands when stripping the wire also. Good luck!
