Aaah! I think I see where the confusion started - or at least where it is at.
Anyway, yes, the MAF is part of the wiring harness. I was thinking of the cable that goes to the ETA, and calling it a harness also (since it's full of wires).
His harness (the one that inc. the MAF) may be good, but the harness/cable that goes to the ETA could be garbage.
As far as opening the lid, I meant the lid to the computer box, and get the part number off of the EA module.
So we're pretty much on the same page
I would like to note though, that in my case the EA was fine, and the ETA was history - that's why I would like to see the ETA harness/cable opened to see what the wires look like......If they are toast, then I'd get a new ETA first - especially since it is the cheaper of the two items (unless you can find a used EA cheap)
