I was asked on the SoCal Land Cruiser Forum for the details of how I setup Anderson Connectors with My Morrflate Off-Road Compressor. Not as elegant as the fully built-in solutions under the hood or adjacent to the hybrid battery but suits my needs for off-roading.

The wiring from the battery goes through a 15 amp fuse with the terminal easily passed through and out the bottle jack compartment. This connects in a jiffy to the electrical plug of the compressor. I added an Anderson connector to the left-over battery terminal clamps in case another vehicle that doesn't have the Anderson connector setup needs to use the compressor. Plug and play!

The fuse box is held onto the battery by 3M tape.

The wiring / Anderson Connector from the fuse box to the terminal stored behind the bottle jack door is Thor's Lightning Quick disconnect Wiring Kit.
This includes the connector to the electrical wiring on your compressor. *** CRITICALLY IMPORTANT: Identify positive and negative cable wiring before you cut off the battery clamps so you put the
correct wire polarity in the Anderson connector.

If you want to use your amputated battery clamps on a car that does not have the Anderson connector setup, then you'll need one more Anderson Connector so you can re-attach them to the compressor electrical wiring. My compressor draws about 85 amps and I went with connectors rated for 120 amps. I also added covers for the connectors.

****IMPORTANT: Attaching cables to the battery. The negative Anderson cable from the jack compartment is easily added to the negative battery terminal as shown in the 2nd picture above.
The positive cable is connected to the outgoing terminal of the fuse box. THE LAST THING you should do is connect a 4 AWG ga battery connector cable of about 15 inches from the fuse box then threading under the battery support bar to the active (hot) positive terminal shown in picture 2. If you connect to the hot positive terminal and try to thread it under the battery support bar to the
fuse box, you will be in for a shocking discovery! (Don't ask me how I know this... Let's just say that EOD guy will not be allowing me to diffuse any bombs!). Also, I believe I had to find the correct size nut for the positive terminal.

This is a great setup that has worked well in the wilds. Airing down at the trail head is very easy with the Morrflate 4 tire hose kit (includes air-hub controller): All four tires quickly air down to target simultaneously. Pro tip: do not leave the AAA batteries in the tire hose kit as it can turn itself on in transport and run down the batteries. To re-inflate I use Morrflate's tire compressor which is very fast and has an excellent duty cycle so you can do multiple vehicles without overheating. Pro Tip: Because the compressor has a very high flow rate it is not advised to inflate a single tire. If you want to use it to inflate a single tire as I needed to do recently for a friend who had a slow leak off roading in Utah recently, just hook up your 4 tire hose kit to all four tires: they equalize and then bring all four tire to target pressure very quickly. Plenty of You Tube videos show the system in action.
