Ford makes at least three
They make one where the connector comes out the opposite side of the vent too
Dime a dozen at the junkyard
I have 3 good used ones my toolbox for testing

I do see now the connector orientation does look a tad different between the two parts. I will check the orientation on my current throttle body before I proceed further

MAF or SD?

More than likely SD, so you probably need the cx1666.

my truck is MAF. The 302 ECM was MAF so I had to convert that onto my 351. Just put on all the parts and put 302 wiring harness on the 351. Mass air flow 351. Works great
