MAT Sensor Plugs

[Rick90lx]

I'm going to move my MAT sensor to my charge pipe, and I'd like to see if there's way to make an extension harness, rather than cutting off the plug and extending the wires. I'm just not sure where to look for the plugs that would mate with the Holley harness.

I'm just not sure where to look for the plugs that would mate with the Holley harness.

Some of those mating ends (Metri-Pack 150/150.2 "Pull-To-Seat" connectors) don't exist, because they plug into sensors or actuators.
Exception: Round 3-pin TPS female mating connector - Delphi 2120-0554 (motorcycle & powersport applications #2120-0216 - LINK).
Exception: Oval 2-pin CTS female mating connector, black - Delphi 12066016 (solder & shrink tube required LINK).
Exception: Oval 2-pin MAT female mating connector, gray - Delphi 12084669 (solder & shrink tube required LINK).

That's what I was afraid of. Thank you.

That's what I was afraid of.

There is a way to make these female wiring connectors (sensor end). If you cut an old sensor in half (first cut the sensor at center of wrench hexagon), you can see where the terminals end (soldered dabs). You can then further trim the remains of the sensor's connector toward the soldered terminal ends (leave a slight "flange" for shrink tube retention). Now solder your wires onto the connector's soldered ends, and shrink tube the new female connector assembly (while maintaining wire/terminal orientation, or use the same colored wires as the mating connector).

Here's a picture of one I made. The top right piece was a pressure sensor/transducer.
The bottom piece is the finished product. I use it at work for troubleshooting purposes.

Interesting, I never thought of doing something like that. I had pretty much resolved to cutting the end off and lengthening the wires. I didn't want to have to do that; everything under the hood is covered in Raychem heat shrink, and I didn't want to cut it up.

Just an FYI for anyone reading this.
The female wiring sensor connector pictured above is for the very common 3-pin sensor/transducer (TPS, pressure, etc.).
However, that particular female wiring connector is commercially available for purchase:

UPDATE: I added some pertinent information to post #2 that should include just what you need.

Thanks for the update Danny. I appreciate you looking into it for us.

You're welcome. This was an old thread, and I don't think the CTS & MAT/IAT mating connectors were even available back then.
