2 TRANSDUCER CONNECTIONS
The Model 10A43’s I/O CONNECTOR mates with Daytronic CONDITIONER CONNEC-
TOR No. 60322, shown in Fig. 1.5 (in Manual Section 1.E.1). Fig. 1 shows how the +SIG-
NAL and –SIGNAL pins are to be wired to the engine. Connect the +SIGNAL line (from
Pin 3) directly to the “most negative” terminal of the engine's coil (i.e., the terminal
which is connected to the condenser, not to the battery). Connect the –SIGNAL line
(from
Pin C) either to the negative terminal of the vehicle battery or directly to the
vehicle chassis (GROUND).
