Why do I get all the oddball problems? A friend had a 2023 RTL that he bought new. I added the BRP trailer hitch kit for him. All was well. Due to other issues, he traded in on a new 2025 RTL. I removed the trailer hitch kit from the 23 and installed it on the 25. He had to buy the extra wire (p/n 219401295) that is required. Prior to the 2024 model year, BRP included the possibility of adding a trailer hitch to any RT. From 2024 up, they removed the 12v power wire from the cargo wire bundle. This additional wire that is now required is piggy-backed into the cargo interconnect harness under the pillion seat and is then only a single wire running back to the trailer harness carrying the 12v power for the trailer module. Here is the problem: everything works great except that the turn signals on the trailer are reversed. He signals for a left turn, the Spyder lights all blink for a left turn, but the trailer right turn signal blinks. He signals a right turn, the Spyder blinks on the right, the trailer blinks on the left. Not that it makes a difference, but he has a freedom trailer. I plugged in my RT-622 to his bike and it does the same thing. In comparing the 2023 and 2025 wiring diagrams, everything stayed the same except for the lack of the 12v power wire on the 25. Any ideas?
