Busaru.com - Subaru Wiring Harness Video Series Part 10 - The newly modified Subaru wiring harness gets a quick test using a cordless tool battery as its power source. The fan and fuel relays are tested as well as the Vehicle Speed Sensor (VSS) and OBD2 wifi adapter operation. If you would like to replicate this test with your wiring harness be sure that you are powering it with a 12 volt power source. You could damage the computer if powering with higher voltage.
