Great I am doing my installation soon. ordering the parts. I got a promotion on the 74 SV at West Marine St Pete. Just the electrical harness I see a difference in numbers. According to Sea Doo drawings I see the 278003974 and you mentioned a 278003684. Not sure exactly what is the difference. I believe it has to do with the split plug. I will watch the entire series, but please let me know if you have any additional info.

Awesome video 😊 I paid the dealer 300 to install mine 😊
