Finishing up stand alone 2007 5.3/4l60e blue and green wiring harness. Where does #14(orange/black) UART serial data and #15(dark blue/white) UART serial serial data on the blue connector go?

They both go to the TAC module. Orange/balck to pin 12, and dark blue/white to pin 13.

I know this is an old thread but, where does the Orange/Black serial data wire off of the GBCM connect? I understand that if you keep this installed you get full output of your alternator. Another member, Fivetears, posted a nice piece about this but diidn't say exactly where to connect this wire.

Thanks
