I think it may be the same one i found in my RA. I believe the conclusion the forum came to was knock sensor had been replaced

im still unsure....it comes from the fire wall to that plug...

which plugs into the manifold loom.....cant see it gooing anywhere else ???

i also thought that the knock sensor plug only becomes a issuse if you go from a V1/2 loom to a V4+ loom..

but V1-3 were the same i thought ???

this is where it comes out the fire wall...

Well mines a version 6 so i could be wrong

v1-2 are the same and v3-4 are the same

v1-2-3 = no

do you know what exactly is diff between the V1/2 and the V3 loom??

i always thought it was only the afm plug that was diff between them and it was the V4 when they changed the knock sensor plug???.......

im thinking it may have something to do with the aiir con maybe?????if so then i could leave it unplugged ???

havent found out what it is yet but im thinking its not too important........

as the loom i went to put in is a RA loom so im thinking its something that is on the standard wrx's but removed in the RA's,

unsure if the sti's have them though

[WRXONP]

why are you going from a Wrx loom to a ra loom ? extra injector ? it would have been easier to just run wiring if it where me .
