After our transmission died in the middle of I-270 in St. Louis last month and after having 3,000 rea$on$ why I never want to go back to St. Louis, I knew I had to get some type of transmission temperature monitor gauge. I found what I was after with the Aeroforce Interceptor.
I opted for an A pillar single pod mount. The Aeroforce provides plenty of cable length to run from the OBD2 port up through the pillar trim and out to the gauge. The unit also comes with an optional cable to run 2 mechanical sensor readings to it, and a 12v power supply. You’ll find that some vehicles utilize power from the OBD2 alone whereas my 01 Taco needed to use the auxiliary power lead.
Here is how my installation went: (Photos below)
1) Figure out where you want your gauge to sit. I’m 6’ tall, but I slouch, so I moved it up and down on the pillar trim until it hit at eye level. Mark the location on your trim.
2) Remove the pillar trim. There are 3 connecting points. A clip on the top, middle and a slide tab on the bottom. Pop out the top of the trim to free the top and middle clips then slide the trim up toward the headliner to remove it completely.
3) Position your pod on the trim where you’ve marked your desired location and drill 4 - 3/16” holes in the corners through the pod and your pillar trim. The pod is secured to the pillar trim with feathered plastic connectors. (This pod doesn’t come with the Aeroforce Interceptor it is an aftermarket unit).
4) Remove the pod and drill a ¾” hole in the area that is covered by the pod for your cables to run through. I would suggest a Forstner bit to give a nice smooth hole, but whatever works.
5) Next run your soon to be 12v power wire down from the top to the area of your interior fuse box.
6) Using something like an “add a fuse”, find a suitable location where power is tied to the ignition. You want power to your unit to shut off when you shut off your engine. I opted for the windshield wiper fuse location. Make your connection to the new add a fuse pigtail. I believe I used a 16 gauge wire.
7) Now the fun part. The space between your dash and the side of the pillar is tight. Tape the Aeroforce plug and your 12v power supply wire together and gently pull up from the bottom to the top of the dash. Try to keep the wires toward the back where the existing cable bundle is located. There is more room toward the back. I had to use a large screw driver to pry open the space for the plug sockets to squeeze through. It will go through if you bend things open slightly.
8) Next plug in the Aeroforce plug into the back of the gauge socket, and plug in the power plug into its’ socket. The “power” plug has 3 wires attached to it. The red 12v power wire, and a green and white wire for 2 auxiliary mechanical gauge readings if you opt to install these auxiliary sensors. At this time I didn’t install optional sensors, so the green and white wires are taped off for future use. Attach the bracket to the back of the gauge and tighten thumbscrews so that the unit is positioned however you want it to be. I put it "level" on the horizon.
9) Gently feed the cables back into the hole in the pillar trim. Align your pod to the holes you’ve drilled into the 4 corners. Attach pod to trim using the supplied feather connectors. Now reattach the pillar trim by sliding the bottom tab of the pillar trim into its’ hole and press the middle and top clips into their receiving slots.
10) Finally plug the OBD2 plug from the Aeroforce into your OBD2 port. Secure any extra cable underneath with wire ties. Start your ignition and program the unit to your liking.
I decided to go with the Red display to match what I had. I found it a little hard to read in sunlight, but with 3 display intensity brightness settings it is readable on the highest setting of “3”.
Now while pulling our trailer I can have peace of mind as I monitor the transmission temperature and other parameters.
I’ve gotta say, this is a great addition to our truck.
