I found it.....
PAG 100 Nissan Compressors KLH00-PAGR0 (Type R) Yellow color Type R = Rotory Vane Compressor
Also found this for reference......
PAG 46 Nissan Compressors KLH00-PAGS0 (Type S )Yellow color Type S = Swash Plate Compressor
PAG 46 Nissan Compressors KLH00-PAGQU (Type F)Yellow color Ford - FX15, FS10 Compressors
The switch panel looks plan from pictures I've see on the web.
Couldn't find a picture of the compressor mount on the web, but the one one the truck looks like an aftermarket welded mount.
I'm not sure if it is factory or dealer installed.
It has the under hood sticker.
Works well, just needs some gas. I want to put a small can of oil just to be safe.
Don't see any leaks. Looks to not have been worked on at all.
Guy I got it from said me never charged it.
