DCA/Power Connector J1
Used to connect VTM to either a vehicle diagnostic connector with the DCA cable W1 or to a DC
power source with the power cable W5. The DC power source is usually the vehicle batteries.
Transducer Cable Connectors J2 TK and J3 TK

are routed through these connectors. Both connectors may be used if a test requires two
measurements to be made at the same time.
