Easy Air Compressor Install in Rear Door!!

[Field Scout]

thanks for the tip, moved jack and placed compressor yesterday, took about 30 min, great idea

The MF-1050 and MF-1052 (available at costco now) are about the same size. I test-fit my MF-1052 and it fits perfect.

regarding the heat question...
There is more clearance in there than the picture shows and even more so if you get a smaller compressor.
This setup is simple and power is not connected until you stop and open the rear compartment. I haven't done a full test but I think it will depend on what compressor you have. Mine was a bit more expensive and I assume more powerful than some others, so it fills tires quick without too much strain and after doing two tires it was nowhere near hot enough to melt anything. Also the whole compressor doesn't heat up, mostly just the cylinder part with the cooling fins. With this mounting option you can run the compressor outside on the ground or from inside the door, depending on the situation.

I never could get the trailer light adapter to work for power so I ran power from the battery back to inside the door following rear wiper power from back to front, works great

I found this RV adapter at walmart. With a little splicing, you could ditch the alligator clips and plug directly into the trailer harness.

Well I finally got around to it and spliced my compressor to the RV socket plug this morning. I could have used the center pin, but that's a keyed accessory terminal. I went with the 12v + accessory blade for constant power. I took my time and probably spent 30 min on it ... easy as pie.

1. Check the diagram on the trailer harness cover and verify which blades are which.
2. Test the blades with a voltmeter. The 12v accessory blade is at about 2 o'clock. The ground is directly opposite at about 8 o'clock.
3. Separate the terminal adapter from the plug housing, and mark power and ground on the corresponding terminals. RV plugs are directional, so matching the blades is important.
4. Cut the positive alligator clip and mark it with tape
5. Cut the negative alligator clip
6. Thread the plug housing onto the wires
7. Strip 1/2" off the positive lead, twist the strands and clamp to the adapter's 12v + terminal
8. Strip 1/2" off the negative lead, twist the strands and clamp to the adapter's ground terminal
9. **IMPORTANT** Insert the adapter into the plug housing and SECURE WITH SET SCREW. If you don't secure it, it will get stuck in the harness during step 10.
10. Plug assembled RV plug adapter into trailer harness and test compressor ... congratulations, you're done.

The compressor definitely runs better with a direct battery connection. I might mount it in the engine bay at some point, but this will work for now.
