connector for knock sensor

[T77911S]

where would I get a connector for this knock sensor

[Dpmulvan]

Amazon, just type in knock sensor pigtail

There are other places online, but I forget them off the top of my head. I think that is a sort of AMP connector.

It is the same connector as used for EV-1 fuel injectors.

It's an Tyco/AMP (Amphenol) Junior Timer connector.

This does not take a Tyco/Amp connector.

It uses a Bosch Compact 1

You can get the kit from Finjector, part number (1 928 403 137 ) The kit labeled SET-1 will work with 17-20 ga. wire

Not easy to find parts in kit form.

Huh, never noticed that before...

Bosch knock sensors are available with 2 types of connectors (and also the "modern" connector can be had either terminating on the sensor body, or with an attached lead - KS-4-S vs KS-4-K1 respectively).

Bosch says knock sensor connectors are either:

2-Pin RB-Kp.1 (F 02U B00 966-01)
Or
2-Pin Jetronic (D 261 205 288-01)

The Jetronic is the same connector as a Bosch NTC thermo-sensor (same family as the 3 pin variant often used for the mag crank/ref sensors), often called a JT connector. Same as many connectors on a CIS loom - eg WUR, AAR. That's the only type I'd seen.

The JT can be crimped satisfactorily with a $15 ratchet crimper with suitable dies for open-barrel terminals and the gauge of wire used. Dunno about the other one.

this one takes the EV1?
does it matter which one I use.
would like to use one that I can easily find a connector for but also works well.

A Junior Timer connector is much more rectangular than that.
(It is surprising how many places the Junior Timer connectors are used. First place I saw them was the crank sensors on the Carrera but now I see them all over. They even use them on my cheap 90's Nissan pickup!)

does it really matter which sensor I get.
been trying to get info on them but not really any out there.

I assume the 2 wire ones are better than single wire for noise

Bosch publish several datasheets, including drawings, fitting specifications and vibration/thermal/corrosion/lifetime specs.

Google "bosch Y.261.K23.205" for the Jetronic connector and "bosch KS4-P datasheet" for the other one.

Apart from the connector, they're the same sensor.

They're all 2 wire, it's a piezo microphone. Doesn't matter which wire goes where, but you need both. The only difference is the connector; which is better for you probably depends on which crimping options you already have.

I ordered 2 of these.
came with connectors so no worries.

also ordered this air temp sensor.
I ordered a M18 to M14 adapter so I can mount it in the IC right above the throttle body.

hope the engine shroud does not get in the way.
