how long is the sending unit cable? I will have need a fair amount in order to run this due to varying conditions under the hood

Asked by: bluebill
Thank you for your question. This gauge actually does not come with any wiring. You will need to supply your own wiring for this gauge.

Can this gauge and sender be used to monitor automatic transmission temp? Will be used in a 700R4.

Asked by: Jim D
Hello, Thank you for your question. This gauge uses the same sending unit found in our transmission temp gauges. You can definitely use this for your application, but will need to locate a port on the transmission to place the temp sensor.

Zach, In the installation instructions it clearly says I should use Teflon sealing compound on temperature senders. Please explain your recommendations to use no sealant or tape.

Asked by: MoonBar2
You can certainly use a small amount of sealant, but it's important to know that a ground connection must happen through those threads. Since the sender is a tapered pipe thread, sealant isn't actually required.

Can the sender (2258) be used without sealant or Teflon tape ?

Asked by: MoonBat1
Thank you for your question. We actually recommend you do not use teflon tape on #2258 as the sensor grounds through its threads and teflon tape/thread sealant can lead to a poor ground connection.

Does Teflon tape interfere with the ground (through the threads) ?

Asked by: Moon Bat
Thank you for your question. The sending unit for this gauge does ground through the threads so using teflon tape or thread sealant can cause grounding issues.

I have a 72 mustang with a 351C and light cluster. I want to install your Air Core water temp/oil pressure gauges along with your mounting bracket. What other accessories will I need to ensure I can keep my factory cluster operational?

Asked by: Doug A
Thank you for your question. You can use a T adapter to install our gauges inline with your current setup. We do not offer the T adapter you would need but if you know the fitting size you need, Summit or Jegs will more than likely have what you need.

What does the back of this gauge look like

Asked by: Joseph6777
Hi, thank you for the question. Our best shot of the back of the gauge would be in the instructions for our universal wiring harness: https://www.autometer.com/media/manual/2650-1797.pdf

what will I need to install this on a 1994 F150 4.9 6 cyl. ? I would like to also retain the operation of the factory gauge. Please advise... THX !

Asked by: RSNAKE2
Thank you so much for contacting us. It's not easy to get to the factory sending unit on the inline 6's in a pickup; it's on the back of the motor so it's best to just leave that alone (which retains the use of the factory gauge). In most cases, we'll install the sending unit in either the thermostat housing (some are ported) or on the water pump (which often also has a port). It's right up front, easy to access and provides a good, accurate reading. Hope this helps!
