04+ Topswap Vacuum/ sensor Help

[Explicit_Spade]

Can some of you kind GPF folk who have top swapped an L26 with the N/A wiring harness show me what you did for vacuum lines and sensors. I think I might have mine set up wrong causing a lean state that my car is having a hard time compensating for.

My main focus as of now is the MAP/PCV sensor setup, but pics and/or detailed description would be great.

TIA.

Is my issue that I didn't get this? W Body Store

I thought those were only for 97-03?

You still need to do something for the map/bcs. Unless you tossed an L32 map on it. Those have the same connector as an L26/L36 and plug right in.

I used the conversion like the wobody store has. just for the BBV though not the other one

How would I do this billboost? The whole vacuum system has me lost.

If I get an L32 MAP sensor I plug it into the wire where the L26 one when and run it where exactly? Right now I have the L26 one run straight to the nipple under the S/C snout.

And a noob queston, whats the BCS?

Pretty much vacuum is easy once you look at it closely. The LIM nipple you used feeds the FPR, BCS and the map sensor. Do that and it's all good.
