Default Re: Comprehensive CSL Intake Thread

Here's a visual of the main engine harness difference between CSL and an 03 Euro harness.

CSL harness on the left, Euro on the right


CSL Harness


Euro Harness


CSL intake flap motor and IAT wiring plug


Euro non intake flap motor wiring


CSL Map sensor wiring


Euro no map sensor wiring (notice the grommet is already there for it however)


CSL intake flap potentiometer plug


Euro MAF plug


Wiring housing internal differences and plugs (CSL first, then Euro)











CSL Intake flap motor wiring hole (just drilled out and plastic grommet (part number of grommet appears to be ending with 1407960)



Happy to provide more photos of this harness if requested.
