How do you take a picture of something that isn't there?

I'll try to respect John by keeping this under six lines:

1) Take the elbow fitting from the BFS TRAN port and attach it to the VCV forward port atop the green cylinder, along with the black line that continues to the transmission modulator. BFS is defeated.

2) Run a line from the split upstream of the VCV center port to the bigger line that tucks behind the fuse box. This goes to a vacuum reservoir in the fender. Mind the step-up adapter for the bigger reservoir line somewhere near the BFS. The option is to replace the splitter with a straight fitting and forego the reservoir. I don't notice a difference without the reservoir but mine is hooked up and holds vacuum.

3) Replace the splitter at the ALDA with a straight fitting to remove the boost signal to the BFS. Or as I did, use the branch to route a signal line to a boost gauge in the cabin.

4) If you want a cleaner engine bay, remove the BFS and associated hardware. The VSV has a wire from the 50*C temp switch by the thermostat. I replaced the temp switch with an afterglow temp sensor for a 602.962 when I upgraded to an afterglow relay. The wire goes to the fifth pin in the afterglow relay small connector.
