I'm adding a custom gauge pod from a VOLVO 240 Turbo. I replaced the old units with new VDO oil temperature, transmission oil temperature, and an outside temperature gauge.

This project needs some wiring modifications and a case to mount it underneath the center air vents so it can look like it was meant to be there.

 

Its kinda huge. Have you thought about mounting them on the a pillar trim?

 

It's the angle of the photo. I never cared for the pillar mounted gauges. I'm still working on the best exact place they will go. Flush with the air vents or further back.

 

What sensors will those work with?

 

Well these are new gauges I ordered from Summit. I'm only using the cluster and plug wires. The outside temp gauge came with a factory sensor. As for the engine oil temp sensor, I'm going to use one from a pre-1990 Corvette. The transmission oil temp sensor, I have some questions on whether to install a sensor at the pan or inline with the send to radiator line.

 

There should be a port on the trans case for the sensor. I forget which side. I thin it sticks out too much at the front of the vents.
