Oops, mistake in my initial reply...

The caps aren't needed on the common MAP wire - you don't want them involved when you're in "stock" mode on the switch. Same for the 520 Ohm resistor, they should bot attach between the LM317 and the switch.

The caps don't go "inline" on the wires.

One end of the 10uF cap attaches to the point where the 3300 Ohm resistor connects to teh LM317 and the other to ground. The 520 Ohm resistor connects to the exact same points.

One end of the 0.1uF cap attaches to the +12 line, close to the LM317, the other end to ground.
