Best power source for fuel pressure meter

There should be a light blue wire with a pink trace under the steering column that is for customer accessories. It is the 4th fuse up in the right hand row (passenger side) in the fuse box under the steering column. Should be a 10A fuse. Although, I think I used the radio fuse and taped that when I installed my ISSPRO gauges.

Continuing along with the gauge questions, did you use the high or the low pressure port on the back of the filter bowl. I have read arguments for both. The higher port is easier to reach and reads only the pump pressure. The lower reads pressure after the filter. I change my filter about every 10,000 miles do I am not overly concerned about pressure after the filter, unless there is something I am missing.

Steve, this really is personal preference. Most of us install the sensor in the post filter port because that is what we are most concerned about. If you change your filter regularly, then there is no issue with installing the sensor pre-filter which as you said is an easier install.
I will be installing the 90 degree bend on my fuel bowl when I remove it in the following weeks to rebuild and reseal it. The reason for this is the HPOP line going to the passenger head is a little to close for comfort the the back of the sensor with the ISSPro and thread adapter coming off the fuel bowl.
I don't think this is a problem for all trucks, but seems to be for mine. If I were not installing the 90 degree elbow, I would be moving the sensor to the pre-filter port.

What I have ended up doing so far is using the upper plug, but still using an ell vertically to avoid the jam up behind the filter housing. For the ignition hot for the meter, I used a fuse tap in the fuse panel inserting in the front wiper fuse so the wire runs inside the fuse pane under the cover.
I haven't decided where I want to tap the dimmer circuit for the meter light yet. Maybe at the light switch. I have it out but haven't probed the wires yet. Mostly it is the awkwardness working under the dash and climbing up on top of the motor.
Thanks,
Steve
