Review on Indicator Damp Proof Independent Automotive Electrical by Scott Reid

Used as an extra fuse box on my '67 Mustang under the hood. Ford is notorious for resistance wire. headlights, distributors and so on. Fuse box to supply 30A relays for resistive circuits. I used wire #4 from the battery to the fuse box. Positive and negative is #4. Built-in fuse within 10 inches of battery. I now have a full 12 volts for these circuits. Because of low voltage, the headlights are now white instead of yellow. Hei gets 12 volts instead of the usual 9.3 volts. Windscreen washer bag, easy to connect, looks good.
