I received my gages today I got a Pyro meter, oil, and diff temp gages.
I know how to install the Pyro but I need help with the other two gages. If you have pictures it would help
The gages are going in a 2006 F-350 PSD 4X4

 

This is what I have for instructions.
Do I need to weld the nut in the oil pan and diff cover or is there a better way?

1. Install temperature sender. THREADS
A. Water Temp: Install temperature sender (included). Purchase of additional fittings such as metric or hose adapters may be required.
B. Oil & Trans. Temp: Hole may have to be drilled and adapter nut (included) welded or brazed in pan. Be sure there is
adequate internal clearance for nut and sender. Sender should automatically be grounded when installed. If not, proper
ground connections should be made. May use #2260 weld on bung on steel pans (not included).
C. Cylinder Head Temp: Head must be drilled and tapped for 1⁄8" NPT hole. Sender should be grounded automatically when
installed. If not, proper ground connections should be made. Be sure not to drill all the way through.
D. Diff. Temp: Install temperature sender in 1⁄8" NPT sender port on cover if available. If cover does not have a port, remove
cover and drill and tap a 1⁄8" NPT hole or, drill and weld, or braze, adapter nut (included) in cover. Proper ground
connections should be made by running ground wire from bolt in cover to chassis, being sure to leave enough slack in wire
for suspension travel.
2. Route 18-gage wire through firewall. If a new hole is drilled in the firewall a grommet is recommended. Connect one end to
terminal post on temperature sender, and opposite end to sender (S) terminal on back of gauge.
3. Route 18-gage wire from center terminal GND (-) on back of gauge to good ground near sender.
4. Connect wire from ignition switch to ignition (I) terminal on back of gauge.
5. Reconnect negative (-) battery cable.

 

There are a lot of gauge install threads in the 6.0L forum, you might want to go search around in there.

Most people I have heard talk about differential temperature probes have installed mag hytec covers which have a temp probe port in them already.

I believe most people get oil temp off the filter cover or something like that.

 

I have been looking at the hytec covers for the diff probe, I think that will be my way to go.
As for the oil I don't think the plastic cover for the filter will work. I could be wrong.
Any more input???
