AMBIENT (OUTSIDE) TEMPERATURE SENSOR & HARNESS LOCATION
I'm adding an overhead console to my truck. Luckily, all the wiring necessary is in the connector behind the right kick panel that the console needs, except that there is no outside temperature sensor on the truck for the temp display in the console. Could someone with a 2002-2004 Lariat please take a look at their outside temperature sensor and let me know how it mounts and how the wire harness from it runs and where it connects up with the next harness. The sensor according to my EVTM manual looks like it is located behind the grille on the driver's side of the truck. The harness, according to the manual looks like it runs along the driver's side frame towards the back of the engine compartment, but I can't be sure--one picture of it shows it running along the bottom of the radiator support, so it might be on the passenger side. The connector at the far end of the harness, according to the same EVTM manual is located at the rear of the engine compartment, but there is no picture for the exact location of that connector. The rear of the engine compartment is a big place, and I really do not see any unused connectors there. Any help or pictures would be appreciated.
Ron, I don't have an '04 and I don't have a Lariat. But I did add an overhead console and the ext temp sensor.
Here is where it mounts:
The mounting holes already exist. The wires for the ext temp sensor won't exist. You will have to run them. I just spliced on some 18g wire I had around, and you can see how I looped it up and through the radiator support. Then I ran around the side of the engine compartment, and through the firewall, then up the drivers side A pillar to the overhead console. Done!
Later I had to run a VSS wire, and I followed the same path from the ABS harness and then up to the console. I suggest you run a spare wire now. I'm not sure what console you are doing, but I needed that wire.
Thanks for the picture Bill. I see the 2 holes where the sensor mounts, but I'm looking for the plug that the sensor jumper harness plugs into. I got the jumper harness from Ford. It's about 2 feet long. The temperature sensor plugs into 1 end of the jumper, and the connector has the 2 small "****" that go into the 2 holes to mount the sensor itself. It's the other end of the jumper that I'm looking to plug into another harness. Luckily, my truck had all the necessary wires for the console to work. Everything works except the temperature. My truck (XLT) is evidently one of the few that has a Lariat dash harness in it, possibly because the truck has a power driver's seat & adjustable pedals--I think they're standard in a Lariat.
There must be someone here that has an 02-04 Lariat---Nobody willing to help ???
My 99 has it (looking at picture) above and behind the spot where you will mount the sensor. Blank plug with dead end cap. Real close to the headlight drivers side.
Thanks for the reply Bill, but I think what you see is the connector for the DRL (Daytime Running Lights) resistor. It's bolted to the panel behind the driver's headlamp and faces upward with 2 male pins in it. It is shaped like the number "8". Mine has no dead end cap on it--it is bare--you can see the 2 pin type terminals. The connector I am looking for is round shaped, about 3/4" in diameter, with 2 terminals in it. Which one do you see, the round one or the number "8" shaped one ???
I think you're right. I just checked the wire colors and they match drl and not the temp sensor. The wires for the sensor are lb/og and gy/rd. According to the book it says "lh front of vehicle." I could not see it on mine. But it is raining and dark outside right now. It should be right in that general area if you have it. The wires come out of one of those three big plugs under your master brake. They are bolted thru the firewall. Maybe you can follow it from there? lb/og is the same color on either side of the plug but the gy/rd goes in pk/og (inside cab) and comes out gy/rd (engine compartment). gy/rd is in the center connector pin 17. Just by the way mine does not have that option so it isn't anywhere. I am going strictly off the shop manuals. Hope it helps.
