TOAD WIRING INSTALLATION: Fig. 7 & 10
a. Connect one wire from the Vac Brake ® solenoid to a suitable ground. (either wire)
b. Install the dash switch in an inconspicuous and easy to reach place, on the center of the dash, to the right of the driver.
c. Connect the remaining wire of the solenoid to the middle pin of the dash switch. Fig. 10
d. Connect an ignition “HOT” 12VDC feed wire to the terminal on dash switch as shown in Fig. 10.
e. Connect a 12VDC feed a wire from a constant 12VDC source to the remaining terminal on the dash switch. Fig.10
BASIC OPERATION SETUP AND PRELIMINARY TUNING BEFORE RV INSTALL
TEST WITH VEHICLE “RUNNING” AND VACUUM PRESENT IN THE SYSTEM FROM TOAD ENGINE.
Adjust the pedal speed by turning the solenoid "AE" and "BE" ports "clockwise" until all the way "seated" closed. Fig 5 There should be
no action, when fl ipping dash switch, with the ports turned clockwise and seated. Next turn the "AE" port ½ turn "out", then turn the "BE"
port out all the way. This should result in faster "pull down" and "slower release" of the brake pedal action. Adjust to the desired skill
level of pedal movement with ¼ turns on each port. You can now drive and test the system, by fl ipping the dash switch to stop
the vehicle while moving with the Vac Brake
® . Test at idle speed fi rst, then increase speed.
TESTING AND TUNING THE SYSTEM ON THE TOAD ®
CAUTION: ALWAYS PERFORM THIS TEST IN A SAFE CLEAR AREA. ALWAYS BE
PREPARED TO USE YOUR FOOT TO STOP THE TOAD VEHICLE DURING TESTING.
a. Start the engine of the toad vehicle, making sure that the Vac Brake® does not apply. If the Vac Brake® applies, verify the toggle switch is in center
position.
b. Push the toggle switch to the momentary position and this should apply the Vac Brake®. Releasing the switch should release the Vac Brake®.
Note: (Especially on Jeeps) To get a true braking test on the toad vehicle, once up to speed (10-20 mph) shift from drive to neutral, then press and
hold the toggle switch to the momentary position. The vehicle should have a steady braking pressure being applied. When the vehicle comes to a
stop, put the vehicle in DRIVE, give it a little throttle and let off. The vehicle should move forward as you give it throttle, and stop when you let up.
c. To balance Vac Brake® power, repeat the test in step b. moving the pedal bracket cable attachment up or down to compensate for to much throttle
or to little throttle, respectively, needed to move the vehicle. Each inch up decreases power by 10%, down increases power 10%.
THIS UP & DOWN LEVERAGING OF THE CABLE CONNECTION POINT IS THE STRENGTH ADJUSTMENT. Fig 1
d. Vac Brake® application speed is adjusted with two needle valves built into the Vac Brake® solenoid. The “AE” needle valve controls the speed
of Vac Brake® release; “BE” needle valve controls the speed of Vac Brake® engagement. We recommend the release be slower than the
engagement. THIS VACUUM FLOW ADJUSTMENT CONTROLS BRAKE APPLICATION SPEED AND RELEASE SPEED. Fig. 5
e. To test the anti-theft toggle, turn off the engine. Flip the toggle to the engaged position (off center, and will stay when you remove your fi nger).
Start the engine, and the Vac Brake® should apply itself.
Automotive Relay Note:
If the towed vehicle's brake lights will work with the key off, there is a possibility that the towed vehicle's
battery may be drained after towing as the brake lights will be activated each time the brake pedal is depressed by the ToadStop. To
keep this from happening we have included electrical parts (relay) with the kit to automatically disconnect the vehicle's brake lights when
the key is off. The only change you will notice to the towed vehicle is that the brake lights on the car will only be activated by the brake
pedal when the ignition is in the "on" position.
FINISHING ELECTRIC AND VACUUM CONNECTIONS TO THE FRONT OF TOAD VEHICLE (Fig. 10)
a. (RECOMMENDED) When using the relay, cut the brake wire that is HOT when the brake pedal is applied. Connect a wire from the end of the
