Yes your harness isn't modified in anyway there thats the way they came form the factory. The way I checked for voltage on mine was to disconnect the plug on the harness (the one at the front of the motor) and I checked for voltage there as well as checked for voltage at the ecu (the voltage is extremely minimal maybe 1 or 2 volts). When I saw voltage at the plug coming directly from the ks and not at the ecu I knew somewhere in my harness there was a short. Therefore I bypassed the harness and just added two wires running straight to the ecu.

BTW my problem ended up being my fuel pump AND my maf
