Im measuring for the big three but have some questions. From the alt to battery. On my truck it goes from the alt to the relay box then to the battery. Due i just measure from alt to battery and bypass the relay but leave the old wires where they are? Also the eng to ground does the same, goes from eng block to the relay box to chassis. due i skip the relay box ? Im upgrading a dodge 03 ram 1500 with the 5.7 eng.
