Knock sensor connector (1 Viewer)

[Malleus]

In the process of removing the engine harness during the headgasket R & R, I managed to break both knock sensors. Actually, the male connectors of the sensors crumbled in my hand. O'Relly came through with the replacement sensors (I cheaped out and didn't buy Toyota sensors). However, I also managed to pull the lock tab off of one of the engine harness housings. Fortunately, they are still available: 90980-11166. The bad news is that when you buy housings from Toyota, you only get the housing. Not a problem if the the housing isn't sealed, but all the engine harness housings are.

So, you are left with one of the following scenarios:
a) find a 1995 (or so) Camry (or something else from about that same era) and splice it in
b) harvest the terminal and gland (the sealing part) from the old housing (not a big deal, but does involve surgery and the help of the Wiring Harness Repair Manual, RM-1022E)
c) order a new housing, terminal and gland from Ballenger

d) or, even simpler (but not as elegant; see a) above), buy a new pigtail from Ballenger and splice that in

How much wire is left on the harness? Option D seems like the cleanest / easiest

I picked this up but haven't installed it yet...

You are too kind, but I had already ordered replacements by the time I got around to posting.

Toyota was really stingy on the harness length on that side of the engine. The wire broke at the connector, so I'm hopeful I can move the wire into the connector by the length of the engagement in the housing, maybe 1/4"?

You know, I never even thought to look there. The list of 80 parts he has grows by the day.

Napa sells pigtails also

If you figure it out, let me know. My best guess is that the O'Reilly sensors are not quite sending the right signal, and I need to replace the one I installed. I also replaced the front knock sensor and the pigtail. I spliced the front knock sensor to the rear, and the rear sensor is currently passing a good signal to both pigtails. I'll get around to buying an OEM sensor one of these days.
