i thought i would hijack this thread instead of strting a new one.
i picked up my 2001 Patrol 3.0ltr TD yesterday, and it came with a Boost guage and another digital guage that i did not know what its for

if someone has any idea that would be great. It has an in and out temp.

is there any other aftermarket gauges i should be thinking about getting put in?

and types of guages does everyone have for their dual battery systems?
