Need your help. Both my knock sensors have failed (codes came up but no check engine light). It's beyond my capabilities to replace them myself, but I'm going to have a trusted shop fix them for me.
Trouble is, I/the shop/their supplier/the local Infiniti dealer are getting different results for what the knock sensor harness looks like. I want to make sure we order the correct part so the car doesnt sit there for days while the correct one is mailed in.
To save several hundreds, I was going to get the parts online and have the shop install them. Something like this for 25 bucks-

Note that there it's one connector to one connector, and I'd order two, each would be completely separate.
Weird thing is, the Infiniti dealer seems to think the harness is completely different! Here is a fax they sent, their harness is circled in the lower right-

Note that it's a single piece that branches off to each bank behind the engine. They're asking about $180 just for the harness and several hundred for each knock sensor!
I cant even find a similar looking knock sensor harness for my car anywhere else. Is the dealership correct?? Or am I fine buying an aftermarket part that looks like the one above? And any trusted non-dealership brands you recommend?
Would love to know what the actual part looks like, esp from people who have done this themselves. Thanks!
