A1190 is an oil hose but this kit needs an electrical wiring . Where to find the plug needeed to connect on sender unit ? thanks .

Willys Jeep Parts Tech:
The electrical connection you need to pick up locally.

Does the gauge include red light as original?

Willys Jeep Parts Tech:
This does not have a red light in it. It would not.

Will this gauge fit my 1957 CJ-5 with a 6-Volt system?

Willys Jeep Parts Tech:
Yes, but you would have to drill a hole in your dash since its a CJ-5 to mount.,

I ordered and received this kit, but i have no clue (and no instructions) how to install it. I have searched Youtube, and asked questions in some of the Willys forums without any luck. Can you please direct me to any resource that might help me with this? INSTRUMENT PANEL OIL PRESSURE GAUGE KIT (6, 12 OR 24 VOLT) FITS 41-66 CJ-2A, 3A, 3B, M38, M38A1

Willys Jeep Parts Tech:
It comes with a set of instructions. Please email mike@kaiserwillys.com to help you out. Thanks!

I have a new 24 volt 1951 M38 oil pressure gauge. It did not have the double resistor adaptors on the old unit. How do I install these correctly on the new oil pressure gauge terminals? How are they attached to the wire harness?

Willys Jeep Parts Tech:
You would wire these in direct. See the note in the item description on wiring it up for the 24 volt. This is a stand alone gauge and sender.
