Using Heavy Duty Modulite, Part # 119190 on 2008 Toyota Rav 4


Will this harness work on a 2008 Toyota Rav4? I know it wont just plug into the existing harness, but will it work on that system?


Expert Reply:

If you do not care to use the Tow Ready Harness, part # 118412 that plugs in to the connectors behind the taillight assemblies, you can certainly use the Heavy Duty Modulite Wiring Harness, part # 119190.
The Heavy Duty Modulite Wiring Harness is not vehicle specific. To make the required connection to the positive battery terminal, I would also recommend the Modulite Installation Kit, part # 118151. To locate the correct circuits behind the taillight assemblies to tap the modulite into, you might find a circuit tester like part # 40376 helpful as well.

We offer the Modulite, the install kit, and a circuit tester in a kit, that part # is 119190KIT.

We have an installation video that you might find helpful, I will provide a link below. The video shows the Modulite being installed on a different vehicle, but the procedure for locating the correct circuits and the connections at the battery would be similar enough to provide guidance.
