Truck is a 2010 Pete 388 and it was ordered as a basic fleet truck with the minimal gauge package. I am wondering if there is a place in the harness to tie into to add a temp gauge from the sensor the ECU reads? If not, I am open to an aftermarket gauge with a temp sending unit, but I would need to know where on the engine i can access a port to add the oil temp sending unit. (it looks like most are 1/8 npt)
any input would be greatly appreciated!

The factory gauge would be the easiest solution.

Next to that, you should read thru the the thread that tree98 posted.
