I recently got a JB3 2.0 PNP. I would like to upgrade it to a JB4, as
per the upgrade through the BMS website. I looked at the upgrade instructions and noticed you have to modify the JB3 harness for it to work. The first question I have is there are 2 tutorials listed on the BMS website. The second one states "This is the only install change from the JB3PNP." Does this mean I only have to preform this (2nd) modification for it to work? The second question is, is the second tutorial (the one referring to the green clip) modifying an oem bmw harness?

I am pretty good with electrical, I just want to make sure everything is right. Does anyone also know whether the upgrade kit comes with the necessary wires? Thanks in advance!

The upgrade kit comes with everything you need. You need to add the supplied power wire, and then re-arrange 3 wires from the large black sub connector. You can grab the upgrade of my site, and PM me if you have any other questions.

Its a 15min job and pretty simple.
