Hey @philip g here are a few pics. Can’t really see the harness too well by the cats, but the others show them pulled through. May not work on yours, if yours doesn’t have PAIR. Foreign market stuff is different.
I did it in mine. No extending the harness, If I remember correctly. This is a no cutting, welding, etc solution. If you want pics I can get some this afternoon.
Definitely wouldn’t be that much.
Regardless, your easiest route is to put the 02’s in the header. Get rid of the PAIR. You can use a 95-97 coolant hard line, or just use a coolant hose to get around where the PAIR was. Harness is long enough to reach there. Should run like a top with no CEL...
