Stand alone harness to stock wiring - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I am wiring up my 8.1 Vortec swap. Pcm has red blue plug combo and is almost identical to red/blue plugged ls. Modifications to stock engine harness according to LT1SWAP.COM.

I have it all wired except the brown and brw/wht wire that originates at the acc terminal of the ignition switch and terminated at the voltage regulator.

Standalone harness seems to have all the wires to alternator accounted for other than b+.

The brown feeds the accessories also. Where is this power applied from? Does it come through the switch from pink to brown? I'm pretty sure not.

Can someone lay some knowledge on me?
