I bought this gauge with an oil pressure and boost/vacuum gauge after buying a fuel pressure gauge for my Foxbody Mustang. I was impressed with the fuel pressure dual readout so much that I decided to ditch the old school analog mechanical gauges I had in the car for these ones even though they are "designed" for trucks. I really enjoy full sweep gauges and I like the digital readout as well. As far as I know, this is the only gauge like this in the market. A neighbor saw them and wants them for his truck.
The wiring was easy and straightforward. I like the dual reading and the gauge seems to be great in response and seems to be accurate enough for me to get a feel of the engine temps. The factory brightness for both day and night are fine with me - and I still can dim it more if needed. I like that I can see the face in the daylight even when driving into the sun.
I didn't encounter any install issues and everything worked perfect the 1st time. Read the instructions are verify what you get versus what you need - you might need an adapter or bushing to set the sending unit into the engine, but knowing about it before you start and getting those pieces makes it a quick and easy install.
