WIRING: STANDARD INSTALLATION
Applications with Seat Lift Feature
The wiring diagram presented in Figure 3a shows a typical installation for ap-
plications with the seat lift feature. This installation includes a single-ended,
3-wire 5k
Ω potentiometer throttle, which is used with a reverse switch. With a
wigwag throttle, a reverse switch is not used and Pin 17 is left unconnected.
In this example, one set of B+/B- pins is left unused because the logic
circuit is wired directly to the vehicle’s battery pack.
Note: When using the B+ pins (10, 11) an appropriately sized fuse must
be added to the circuit to avoid damage to the controller.
