I recently did a topswap on my 04 and now I'm not sure that my vacuum system is set up right. I'm on an L26 wiring harness because I didn't think I had to switch, now I'm thinking I need to. The reason for this is my LT B1 % is in the red, which is generally a pcv sensor from what I've read, but my PCV and MAP appear to be the same sensor on an L26.

Anybody have any good pics or a detailed description of how they reused the stock wiring harness or should I just pick up an L32 harness, hoses and sensors.
