I just put the Indian extended reach heated seat on my 2020 Chieftain, replacing the stock Rogue non-heated seat. When I installed the new seat I saw there was no place to plug in the 2-conductor plug for the heat. Looking back carefully at the instruction sheet I saw where they barely mentioned an adapter harness thingie that would be required to plug in for the heat. It's part #2415036. They recently weren't even listed on the Indian website. I was told that was because Indian had run out of them and they were in production again. So I ordered one of these harness adapters through my dealer and, just today, got my seat re-installed with the heat wire plugged in. One end of this adapter harness plugs into the big multi-pin connector (shown in B Joker Card's first photo above. The other end of the adapter is what you plug the 2-conductor wire from the seat into. BTW, that plug in his second photo looks like it would accept the heat wire's plug. But I didn't have one of those on my bike. I needed the adapter.
