VMAC recommends that all electrical connections (with the exception of the clutch connector in the engine bay) be soldered and shrink wrapped. We do not recommend using bullet connectors. Figure 1 shows the location of the SEIC Blunt Cut Wire Harness where the majority of the Throttle Control connections are made.

This will be powered when compressor is turned on. 2) With the engine off, key in the run position and park brake applied, measure voltage on the RED wire running to the WHITE interface connector (Should be +12V DC). This will be powered when key switch is on. 3) Measure the resistance of the GREEN ground connection from the throttle controller to the vehicle battery’s negative terminal. This reading should be less than 1 ohm. 4) Measure resistance between WHITE interface connector ground terminal and battery negative terminal. This reading should be less than 1 ohm. 5) Check the BLUE wire from the throttle controller, ensure it is a good soldered connection to the BLUE with GRAY stripe wire in the blunt cut bundle. 6) Check the WHITE wire from the throttle controller to the “clean tach out” circuit CE913 (see wiring diagram) at the blunt-cut harness. Ensure this is a good soldered connection. Check Pins 4) Check Ground 1) Measure Voltage 2) Measure Voltage 5) Check Connection 3) Check Ground 6) Check Connection
