Parts Needed to Convert 4-way of 2015 Toyota Highlander to 7-Way

Question

Question:

I have a follow-up question. If my trailer has breaks but I wanted to use a wireless break controller e.g. 90250 will adapter #37185 be sufficient for me or do I still need to run some extra wires?

If your trailer does not have brakes all you would need is the part # 37185 as an adapter to convert the 4-way to a 7-way.

If you do have trailer brakes you would need the # ETBC7 instead of the # 37185 and a brake controller. This kit comes with everything needed to wire up the 7-way and install a brake controller.

For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup.

Yes, if you wanted to use the RF Brake Controller # 90250 all you need is the # 37185 instead of the # ETBC7. With the 37185 all you would need to do is plug in the 4-way section of the adapter and then run 10 gauge wire like # 10-1-1 (sold by the foot) from the black wire through a circuit breaker like part # 9510 to the positive post of the battery.

Maximum amperage draw for 4 Brakes that are 10 or 12 inch diameter is 15.0 to 16.3 amps at 12 to 13 volts. The 14 gauge wire may be sufficient but for maximum braking effectiveness at full load capacity. I would opt to run 10 gauge wire. Larger wire…
