Puma 12v compressor on rear power outlet?

[TNRunner99]

I'm wondering if the rear cargo outlet in the 3rd gen is capable of running a 12v Puma compressor or will I just blow fuses. Planning on pulling out the plug and hardwiring it to the stock outlet cable.

I'm finding the compressor pulls 30 amps but don't know what the rear outlet can hold or the wattage. I'm almost clueless about electrical when it comes past volts.

Quick electrical 101: volts x amps = watts

Therefore watts/volts = amps

That rear outlet is only rated for ~150w if i remember correctly, which assuming 12-15volts (car on/off) is only 10-12 amps max. You'll want to probably hard-wire the compressor to get best performance. You will blow fuses trying to run it off that outlet in the back, 30A is a decent sized draw.

No that will not handle it at all, that outlet only handles about 10a max. If you want it powered in the back you're probably going to need an 8ga wire from the battery just to run the pump.

Look in your fusebox for the fuse that the outlet is on. That would tell you what the plug is rated for.

As said, it won't handle 30 amps, but that's where you could have looked. There's always just plugging it in and trying as well. If it blows a fuse you have the answer.

Normally decent advice, but these plugs are fused at 15A for the three of them. However, the outlet plugs have a fusible link installed in the base of each outlet. If you blow one of those, you have to replace the outlet.

So I wouldn't try that or trust the 15A number.

Sweet Thanks for the advise. I was hoping for an easy solution. Guess I will run an 8ga wire from the battery to the back. Now I have to figure out how to wire it all up. Guess I will need a relay and a switch on the dash.

Make sure to fuse that new wiring as well.

Ive got that same compressor and will guarantee it won't run off that rear cig lighter. It's a great compressor, but a power hog!

Yes be sure to fuse the wire as close to the battery as possible. Also consider if you are planning on ever running anything else back there such as a fridge, lights, inverter, sub woofer, whatever, make sure to run a wire that handle your future power needs. You don't want to run an 8ga wire now, only to have to run either more wires or rerun it in a bigger gauge later.

Thanks for the tip. Read your build thread but couldn't figure out how you got everything set up. Looks pretty complicated but a clean install. I like the switch you used. What relays did you use for the switch and compressor?

Great Runner by the way. That has always been my favorite color combo.

Thanks for the compliments! Honestly the only thing I don't like about my runner is the color! When I went looking, I wanted anything but black (black truck in the desert... :mad2, but this was the only one I could find with all the options I wanted. lol. Oh well, I've loved every minute of it.

Let me see if I can explain my set up for ya, its pretty basic really, setup just like any 12v circuit with a relay.

The switch runs from the battery - to the switch - to the relay with 18 gauge wire. All this does is trip the relay on and off. On the ground side of the relay, it runs through a pressure switch that opens up at 100psi, and closes at 75psi - then to frame ground. This is what cycles the compressor on and off depending on pressure.
For the actual power side of the compressor, I ran a 2guage cable from the battery to the back cuby where I've got everything mounted. It splits to my inverter, and to the air compressor relay. From the relay it runs over to the compressor. Everything is fused of course, a couple amps for the switch circuit, and I think 60 amps going to the compressor.
The relay I used is a ford starter relay style, but its designed for constant duty load, like this one.... RELAY

It's also worth noting, that on my setup, I split the tank from the compressor, I also ditched all the original regulator and pressure switch. (The regulator never worked from day one.) I ran the original tank for a long time on my taco, and ended up going to a smaller tank on the Runner just for installation reasons. In fact I just installed it finally last weekend.

Hope some this helps and its not TO confusing, feel free to ask any questions if you want, or want to see any pics of it.

Sweet Thanks for the info and link. I'm slowly going to work on this setup. Saving money for the compressor first. I'm gonna check at Pepboys and see what all parts for the setup I can get there first.
