Rear Differential Temp Sensor Harness

[Stang24]

The portion of the harness running through the port in the truck, are those for the rear abs?

I’ll be taking the rear seats and the trunk lining out tomorrow and will port the pictures.

Update for this? Did you ever get the axle temp sensor harness figured out?

I have not. Have you made any progress? I just installed the PP radiator to complete the PP engine upgrades. Next step is the rear differential cooler. I have the harness that controls the pump as well as the diff temp sensor. I need to remove the back seat and locate the harness the temp sensor plugs into. Slow process. I can say the PP radiator made the difference in my oil temps. The algorithm that calculates the oil temp is tied to the the coolant temp. We ran the roval at Charlotte two weeks ago and oil temps never got above 225. Rear differential cooler is all I need at this point. Will also be adding the DH Track Pack rear diffuser at the same time.

I plan on doing the upgraded radiator then if that’s what controls the oil temp. I already did the oil cooler. This is the part number for the PP radiator regardless of its auto or manual? PR3Z-8005-A

That’s it. I ordered mine through oemfordpartsoulet.com for under $300. The PP radiator has a 31mm thick core verse Non-PP at 18.5mm core. Easy swap. Make sure to vacuum fill the radiator.

Wierdly i am struggling to find the part thats linked to this number but i am now sure i am looking at the right harness.

the reason why you are having a hard time is because that is an engineering number. i looked up that engineering base number using my DH VIN and found this for that harness: PR3Z-2C011-E. due to the fact every DH has Magneride, and only the DH has the differential cooler, if that is the correct harness for the diff temp sensor, it will have unused plugs where the Magneride dampers would normally plug in. i also managed to find a PDF from Ford Performance that lists all the parts used in the Dark Horse R, and this line caught my eye

I have a question for you, i plan to add a differential cooler. I have magnaride and pp. am i prewired to just add the oem pump kit.

PP GT with Magna Ride (Not a DH)?

You are adding the OEM rear differential cooler and pump?

Added the temp sensor a few months back which now display the temp on my dash with the rest of the gauges. Had to update the harness to the PP harness to accompany the sensor but was no big deal. I’m currently in process of adding the OEM diff cooler as well. Same cooler, lines, pump, and hardware from the GT350 and GT500 but at a much cheaper cost. Purchased the pump, cooler, and lines off of eBay from a 22 GT500. I don’t believe your car has the harness to control the pump. Mine did not. MMR makes the connector(777519) to run the pump which will need to be wired in correctly along with a switch to activate the pump unless you’re going to run a thermal switch. Additionally, for the cooler to fit and for air to pass through, you’ll need to change to the DH lower rear valance panel along with the lower rear splash shield and the assorted hardware. It sounds like a lot of work but it’s not bad. I have all the parts and plan on doing the install in a couple of weeks. In all, it cost me less to do the OEM install with all the additional hardware than to go to an aftermarket kit for $1500.

Thanks for the info, yes GT, pp magnaride. The plan is to install the steeda dif cooling kit. I need to climb under the car to see what connections are there. I do know i have a diff temp. sensor.

I did some homework and started taking the car apart. I have a GT W/PP, active exhaust and magnaride. I found a diagram for my car and the harness you have that is missing 3 pins, I have all of the pins on the feed side, but I am missing pins on the receiving side that feeds under the car. That harness controls the active exhaust and the EVAP canister as well. On the diagram its labeled 14B599, I circled it in red. I need that harness, does anyone know that part number. Thanks

 

[Cool66]

Great find! Where did you find that diagram? I have a harness and will look when as soon as I get back home to see if it is the correct harness.

 

[Timry2]

It was in the shop manual from https://www.factory-manuals.com/, and I had to do a LOT of reading.

 

[Timry2]

Cool66, would you be able to post pictures of your harness # PR3Z-14A411-B . Specifically the ends of each plug. I think the one you posted is the one I need. Thanks

 

[Cool66]

Not a problem. It’s with rear diff cooler I’m installing. I out of town at the Petite Leman but will be back Sunday evening and can get I Monday. I’ll message you at that point. Confident it’s the pigtail you’re looking for.

 

[Timry2]

Thanks and no rush. That’s a nice get away, enjoy and safe travels

 

[Cool66]

This is my harness. Take a look and see if this works.
