And I would bet that if you were to remove the pan, you would see more than a thin film of oil in the bottom of the pan and if there were any foreign debris, it would still be there as the extractor tube does not create the same "flow" that regular draining does.
Do what you want to do, but I...
None of the switches are rated high enough for the load of the compressor. (Just like a winch)
The compressor is wired to the battery and relay, the relay is wired to the upfitter switch, so the upfitter switch is just turning on the relay solenoid, which controls the power to the compressor.
I went with Mickey Thompson Baja Boss AT's (D load rating) and I am happy with my choice, they look fantastic, ride smooth and quiet, but I did lose about 1-2 MPG, most likely because of the extra weight.
Ok, let's think this through...
The extraction is done through the dipstick tube.
The dipstick is exposed to the oil in the pan by the tube stopping short of the bottom of the pan, this way the oil can easily contact the dipstick and not be impeded by the tube.
If the tube does not go to the...
I believe it was 4g, but it may have been 6g. I used the amp/distance formula to determine the gauge.
From the battery I ran it through the firewall grommet, down through the drivers side sill and out under the rear trim panel.
I ran power to the rear for my compressor, couldn't stand having to open the hood when airing up.
Modified it this month, added a power box for accessory charging and such...
I use a modified Smittybuilt #2781 single cylinder compressor, which I have power running to the rear, so I don't have to open the hood and use the provided alligator clips and a homemade inflation hose. The power to the rear is handy for charging and running gear.
