How to install the JB4 BT Module to the JB1

I just got the JB4 Bluetooth module. Can somebody help me understand how to install it?

I am looking at this guide but I am confused. Am I supposed to cut 1 of the red wires and splice it? Or....? What is this?

Which Red Wire did you guys cut?

Or Am I supposed to pull 1 of the red Wires out of its socket to attach it to the blue wire? Which means 1 of the pins will read empty?

Nvm Done. Thats the thing with BMS. Their instructions are always somewhat obscure.

So which was it, did you have to splice into one of the red wires. I'm about to get this module.

The unit includes a posi-tap so the bluetooth module can get power...no splicing necessary. Better explanation of the posi-tap linked below.

NOTE: The JB1 must be disconnected completely in order to install the JB4. You cannot just simply disconnect the wire harness.
The Fuse has a RED end and a GREY end. The GREY end of the fuse is for the red wire to be inserted perpendicularly. It grabs the wire rather than you simply just inserting the wire, like you would in the RED end.
Also note the size of the connector case because after you connect the wires to the fuse, the case will need to be closed with the fuse inside.
Insert the blue wire through the rubber hose into the connector case because you start connecting either wire to the fuse.

The blue wire goes into the red end of the fuse. The either of the red wires, 1 of them goes into the grey end of the fuse.

Blue Wire / Red End - The blue wire is pre-exposed. You just plug it into the red end and screw it tight.

Red Wire / Grey End - The red wire is inserted perpendicularly into the grey end and then screwed in. The middle portion of the fuse has a needle which will puncture the wire as you screw it in perpendicularly..

Which red wire? I picked the top Red Wire because thats what the picture shows. However I believe you should pick whichever red wire you think makes it easier to close the case, since the fuse is quite large.

After all of this, download JB4 on itunes and pay 30 dollars for it. Register an account or login with your N54 account. Select the engine (F-Series) in the account preference.

Everything is ready.
