Hey Otis! I've seen that vehicle popping up in our questions lately, how do you like it? The Curt # C57003 you were looking at will do the job. This can be nice if you want a little extension as well. If you don't want that extra wire length added on you can also use the # 20142. Both have built-in resistors which will solve the low power draw problem from the LED lights giving you that fault.

Thanks for the quick reply! Will need to look at both. Goal is to maintain as much departure angle as possible. As to the Grenadier, it is the perfect vehicle for us. We do long distance off-road travels on trails like the TAT and BDRs.

@Otis that sounds like a lot of fun. Does the 7-way angle down in the back like that picture above? The Curt is probably the better option if that is the case since you can bend it up and out of the way to connect to the trailer. The other one would have the length of the adapter plus the length of the trailer connector plugged into it hanging down which will most certainly be less clearance. If you need anything else don't hesitate to reach out, we're here whenever you need us.

@Otis We're looking to make long off-road trips too, looking forward to getting the Grenadier into the field.

Hello, To accommodate a 7-pin connector for features such as electric brakes or auxiliary power, a separate adapter or a wiring harness kit is required for installation. What do you recommend for the 2024 INEOS Grenadier Trialmaster Edition? I need to tow a Taxa Outdoors Mantis Overland trailer.

@Hoskamoen do you already have a 4-way and need to upgrade to a 7-way? You can do that using the # ETBC7.
