Thanks, that's how I have it.The Brown wire goes to the MAP sensor on the manifold, rainbow to TMAP on boost pipe. As instructed in the written directions and confirmed by Steve at BMS by the OP earlier in this chain. That's how I've had mine installed since day one too, no problems.
Good luck, let us know how you like JB4.
I don't hate it, but I'm not in love with it. If the EK1 weren't so expensive and didn't require buying a spare / unlocked ECU I'd have gone that route. I got everything (jb4, BT module, and HKS plugs) for $500, if I'd bought that new I'd have spent what an EK1 costs without the ECU and been disappointed. I think its good value used, but not new.
