I installed an EZ wire harness and a Painless temperature sensing harness for the fan in my 38 chevy. When i hooked up the battery the horn went off and the starter kicked in. I would love to call EZ wire and ask them but they simply suck at customer service. Never return your calls and when confronted they simply give a real vague run about answer. Anyone with idea. I am using a HEI distributor and running a 105amp alternator. I was told by EZwire to run the red alternator power wire to the alternator and also a black bypass wire from the alternator to the starter post. The Painless wire harness for the temperature sensor goes to has a wire running directly to the battery.
