So I was sold a 2019 JCW pro tune exhaust under the pretense that it would work with my 2020 F56S. I started to install it today working the electrical side first. I got it up to the fuse box and then found that there were already wires landed where the directions said to land the black and red wires. So I started investigating and here is what I found.
1) There is a 2020 specific JCW kit 18302475191. I was sold a 2019 kit 11112359631. At the time of purchase the 2020 option did not appear and they said 2019 kit would work.
2) To look at the physical exhaust, they appear to be identical between the two years.
Which brings me to the question of does anyone know the real difference? Is it as simple as the wires land in a different place in the fuse box or was something really changed between 2019 and 2020?
I'm trying to work out my options here. I could a) send back what I have at great expense . Not only shipping expense but for some reason an almost 600.00 difference in price between the years.
b) go ahead and install the exhaust and figure out where to land the wires (are these wires just power and ground?) and hope the tune supplied works with a 2020. c) install exhaust, tune isn't compatible with 2020 and just live with it.

If anyone has a copy of the 2020 instructions for kit 18302475191 I would sure like to know where it says to land the wires in the fuse box.

 

If it were me, and the wires are just a power and a ground, I would land the wires somewhere and be done with it. Just make sure the fuse in the chosen location can handle the required current.

 

I feel your pain. I also have a 2020 F56S and every time I try to buy something to upgrade it, I find out they don't have one for a 2020 yet. When people tell me that a part is compatible even though it is not listed as compatible, I get hesitant, because I don't want to run into the type of problem you are having. I wish I could help. Although mine is a JCW, I don't have the pro exhaust, so I can't tell you where the wires are supposed to be landed. Maybe someone else on here will trace it out on there car and let you know.

 

This is all the info we have, take the oem part number and pop them into the search box, that will come up with section of people talking about.
