Where to Install Diodes when Installing Roadmaster Invisibrake with Tow Bar Lighting

Question

Question:

We have a 2014 Honda CRV Touring. We have purchased from eTrailer.com the Hopkins Tail Light Wiring Harness Kit - HM56304 and the Invisibrake. On Page 3 of the Invisibrake Installation manual it says Likewise, if a plug and play electrical harness has been used, diodes must be installed to protect the towed lighting harness. Most harnesses of this type only have diodes to protect the towed vehicles electrical circuit.. Do I need ti add more diodes? If so where? Thanks

If you check out the picture I attached you will see where to install the diodes on your vehicle to install both the Roadmaster InvisiBrake Supplemental Braking System # RM-8700 and the part # HM56304 that you referenced.

For a diode kit you would want the part # RM-794.

If the check valve came apart with your Roadmaster InvisiBrake System #RM-8700, I recommend replacing it just to be on the safe side. You can do so with Replacement Vacuum Check Valve #RM-452141 which is the black 3/8" valve. The replacement…

Answer 6

Yes. The way that a breakaway switch such as #HM20010 works is that the pin inside holds two pieces of metal apart. Once pulled out it allows the 2 pieces of metal to touch completing the circuit between the breakaway battery and the trailer brakes.…

Answer 7

I'd use a pipe cutter. Pipe cutters will make quick work of the harder vacuum line and won't damage the overall shape of the lines either. Pipe cutters can be found at local hardware stores.

Are you sure the pressure is being lost and not actually maxed out? If the air pressure of the InvisiBrake part #RM-8700 is set to the maximum the gauge will actually spin completely around the gauge and show zero. To confirm that the compressor is…

Basically you want the tow bar to set as level as possible when flat towing. You have 3 inches up and down that is considered safe. Check out the picture I attached that shows what I mean. I also attached a help article that covers how to pick out…

Aside from the diagram in the linked instructions for the InvisiBrake #RM-8700 (see attached) the next best thing we have is an installation video of the Roadmaster Diode 7-Wire to 4-Wire Flexo-Coil Wiring Kit #RM-15247 being installed on a 2021 Jeep…
