Since the trailer is working just fine with another pickup you will want to check any fuses or relays that carry the trailer lighting functions. I tried looking this up in the online version of the owner's manual for your 2017 Toyota Tacoma but there isn't a list for what the various fuse locations are for. These may be listed on the cover for the fuse compartment.

If the fuses and relays look good then you need to use a tester like part # PTW2992 to check the pins on your 4-Way like part # C56349 or 7-Way like part # 22117.

If you are getting the correct lighting signals then the only other thing to do would be to take your pickup and the trailer in to a shop so they can physically inspect what is going on.

The fuse for power steps on a motorhome, like part #LC3658373, will be found on the 12V power wire that runs to your battery bank as opposed to a fuse in the power center like what you find on a vehicle. What you're looking for is a fuse holder…

Answer 9

The only pin that should be continuously showing 12V power on the 7-Way connector on your vehicle is the 12V power circuit which is normally the black wire but not always. In 7-way wiring the 12V auxiliary power feed is carried on the contact at the…

Answer 10

The 4-way on your trailer is what's known as a wishbone connector like part #A35W42B. Two of the wires are the running light circuit which is a little easier to install since you can run one down each side of the trailer. This way you don't…
