Temperature Mirror Problem Solved!

For all of you who are trying to get an answer to the ambient air sensor connections:

As a few other members have mentioned, the ambient air temperature sensor pins at the mirror are 6 and 7. The wires are light green with a black stripe, and brown. However, all you have to do here is trade out your mirror and you are done on the inside.

The wires that you need to connect your ambient air sensor to are mounted on the driver's side fender, right beside the fusebox under the hood. The connector has a purple colored plastic wire seperator on the outside. If you are standing beside the driver's fender looking at the fusebox, the connector is directly in front of you, closer than the fusebox, mounted on the inner fender. Now looking at the right side of the connector (the side facing the cab), you will notice the green/black stripe and brown wire at the top of the connector. Also notice, that on the left side of the connector, you will have 2 blank places. These two blanks are where your temperature sensor wires go. Pull the two rubber plugs out and you can temperarily test your sensor here until you get your wire routed. Preferably, you should call the dealership and order two connectors to crimp on your two wires so that they will stay properly and not back out of the connector. But here it is, I thought this would help many of us who are trying to complete this mod but do not know where to connect the sensor.

Bingo!

That would be the correct two blank spots I'm referring to. I was a little worried not having any picture to post that the description would be a little fuzzy. I'm going to call my favorite dealership Monday and get the correct terminal that fits for that connector so it will be connected correctly. Besides, terminals are very cheap! Right now, I've just got my wires stripped back far enough to reach into the plug, until I can get two terminals.

I took the front grill off and pulled the left headlamp assembly out so that I could run the wires in the front lamp harness. I used wire loom from the sensor just down until it entered the main harness just beside the radiator. It looks completely factory because there is no wire whatsoever showing. The wire follows the main harness all the way up to where it must exit up near the connector. Yes, it was a major PAIN, you have to open the clips holding the harness in place, but it was worth it!

Anyway, If I can help anybody with your questions, just let me know!

You should be able to get the terminals from say, Radio Shack or what not. I order all mine from mouser.com.

Has anyone had any luck getting the part number for the contacts to add to that 10 way connector? I spent my lunch hour at the dealership trying to pick up a pair of contacts but the only thing he could offer was a $50 2 way connector that had 2 of them already crimped to about 12" of wire.

I'm running into the same problems you're having. I DO know that they are a Metri-Pack type connector. From what I've been able to research about them, it IS possible to undo a connector (I'm referring to the pin socket, not the entire plug) that has previously been crimped. I guess it is possible, since the connector SHOULD be able to be spread apart with a small pick. Car-Quest has a pack of 5 Metri-Pack female connectors (part # TA715) that look like they will work. My problem is that I do not have any suitable cable seals that slide onto the wire prior to crimping. I may just go to the junkyard and find a TB and just cut out the connector and disassemble the plug with the pick. Metri-Pack sells a tool to disengage the terminals but a very small pick or precision screwdriver should do the trick. Once I get the connector open and reuse the cable seal, I should be able to recrimp. Let me know if you find out anything.
