Right. I forgot. HO2S relay is a clip on.

I managed to clip off one of the needed plugs while removing the
harness (d-oh). "M plug" I think. Black 5 or 6 pin plug IIRC. Goes to
rear of vehicle. Pretty sure it's for the FP..... ironically.

Maybe setting up relays etc. like the WBX is the way to go. I'll cross
that path when I get there.

But if I use the Jetta fuse box, think of all the room I'd have to
hook up camper type accessories!

(kidding. all the plugs that go to the back look like VW specific plugs)
