If anyone has a 2004-2008 (2.3L engine) in their possession right now, can you do me a favor and look at your engine wiring harness?
I just finished an engine swap (2.5L Ford engine, more POWER!), and I have a single lonely connector that doesn't have a mate. I've looked at a 2010 Mazda3, and the harness is different. I don't know about the Mazda5.
EDIT: This swap is only the block itself, so I'm using all of the original wiring, sensors, intake, etc. So, whatever yours looks like, mine should look like.
So, pop the hood, place your hands on the radiator support like you're going to lean over and look at the engine. Right were your RIGHT hand is, there's a grey connector under the lip of the radiator core support. It's right where your fingers are curled under right now.
It's on the harness that runs along the radiator core support, and it's clipped to the harness, so it can't move. WHERE DOES THE OTHER END GO? I *think* the other end is a male 2 pin black or dark grey connector, and the one I have is a lighter grey, 2 pin female. The connector is oversized, it's closer to an inch across.
