JB4 Bluetooth Connect V3 power?

Having trouble registering with N54tech so I am asking here.

I am getting code 387f which is a power code. the Bluetooth Connect dongle power is supposed to be connected to the TMAP power (per Burger Tuning). The Bluetooth Connect install instructions says connect it to any of the red wires in the JB4 loom (there are 2 red wires). Is there a way to tell which is the TMAP power?

Anyone else getting this code? I thought it was my battery but I replaced it and still get this code. Before I clipped the JB4 board diode and went ISO and installed the Bluetooth Connect V3, I wasn't getting this code. The JB4 power is from the 50A fuse per instructions. Help!

Also your rev3 should be connected to the jb4 red wire.

Yes. Even on map 0. I know its the Bluetooth Connect zapping power. There are two red wires on the jb4 harness loom. I guess ill have to try the other red wire and just hope its the one to TMAP and hope i dont get a code.
