Nissan 2008 Frontier 12 Volt Accessory Circuit Amperage Rating

Question:

My frontier has a 7 wire plug already. Do you happen to know how many amps the black aux power circuit is rated for. Many Thanks

Most 12 volt accessory circuits that are on 7-ways are rated for 40 amps. I would imagine that is what you have on your 2008 Nissan Frontier, but the only way to know for sure would be to find the fuse related to this circuit in your fuse box and look at the fuse rating.

The fuse would most likely be called trailer accessory circuit or something similar. The amp rating should be listed on the top of the fuse so you wouldn't even have to pull it out once you find it.
