just an update, i wired the other power source in with my tach's power source. everything works good except for the thermostat. The fan gets power when ignition is on, but the thermo is way off from what it should be, so i bypassed it for now. need to get a screw or adjustable thermostat controller....but for now it will just be on when car is on. Fan has its own small shroud and i put the stock fan shroud back in place. I know it is a cheap fan, but it pulls a lot of air, hopefully it won't burn out real fast. If so, atleast i have the wiring for a fan now lol. Thanks for the help guys.
