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.

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:

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 !

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!
