Compatibility & fit

• Motorhomes: Gas or diesel (air or hydraulic).
• Towed vehicles: Most flat-towable cars/SUVs/trucks per manufacturer guidance (check your owner’s manual).
• 12V power: Requires an active 12V outlet while towing; add a towed-vehicle charge line if the outlet loses power or the battery tends to discharge on long days.

Basic installation & use

1. Place unit on driver-side floorboard; secure against seat base.
2. Attach claw to brake pedal; verify straight pushrod alignment.
3. Plug into 12V outlet; follow audio prompts; press Auto Position when instructed.
4. Mount breakaway switch on the toad; attach lanyard to the coach.
5. Pair Bullseye monitor and set Brake Type, Pressure (PSI), and Sensitivity; perform a low-speed test pull and adjust.

FAQs

Q: Will this drain my toad battery on long travel days?
A: Typical draw is low, but accessories and long days can drain batteries. Add a toad charge-line kit to keep voltage up.

Q: What if my vehicle has active (non-vacuum) brakes?
A: Choose the Active Brake Type and start around 5 PSI; fine-tune with the Brake Test procedure.

Q: Can I tow if the Bullseye monitor is off?
A: Yes—the unit still functions. The monitor provides visibility and lets you adjust settings from the coach.
