STI / WRX / NA wiring harnes differences ? Seeking experts...

[JeffS]

Hi All:

I'm about to start dieting and installing my donor (2006 WRX sedan) wiring harness using the 2006 "WI" section of the service manual.

Unfortunately the wiring diagram combines all Impreza variants into one big diagram, sometimes dividing into separate pages for the STI, the WRX, and the N/A versions, but in other places just noting the differences within a single page.

So my question.... Are there actually separate harness part numbers for the various models (STI,WRX,N/A)... in other words will I see any STI specific wires in my WRX harness?

Also... Are there any options that would change the harness.... automatic A/C or Headlight leveling motors for instance, or will my WRX harness have all the wires for all possible options?

Thanks... Jeff

The factory diagrams have all of them in one place and will show any differences on each sub section. The wiring in each model is specific to each trim level of Impreza and there are differences in each trim level if the car has climate control or regular AC
