Features
- DESIGNED FOR GM SIDE POST BATTERY AND OTHER THREADED STUD/HOLE BATTERY TERMINALS. 100 feet remote battery kill switch used for 12V equipment that not in use, prevent battery from parasitic drain or as a theft deterrent. Convenient FOB remote control, no need to open the hood to disconnect battery, just a quick button push. The remote is preprogrammed and ready to go out of the box
- HEAVY DUTY, HIGH CURRENT DEVICE. 200A Continuous / 1000A Crank Amps. Enough crank amps to start your car in cold weather. This is a high quality solid state relay with a remote control receiver circuit built into it. This switch lasts 3-4 times longer than an ordinary relay switch. ZOZOMOTORS uses high quality & durable parts only. The current draw of this switch (the remote receiver) is 0.001 - 0.005 AMPS while connected. it's very minor
- VOLTAGE 12V, FLEXIBLE CONNECTION WIRE PROVIDED FOR EASY INSTALL EVEN IN TIGHT SPACE. You can use the provided 2AWG connection wire or copper bars to easily connect the switch to your battery. Recommend install on the NEGATIVE SIDE of the battery. Installation on the positive side is also allowed. This switch can be used to disconnect 12V system including cars, trucks, RVs, ATVs, boats, jet ski, motorcycle and other equipment
- EASY TO INSTALL, WIRING DIAGRAM IS PROVIDED. Package includes Installation Instructions with Wiring Diagram, Relay Switch with Wire Harness, 2 Remotes, 1 Side Post Adapter, 1 Connection Wire 2AWG, 2 Connection Copper Bars, 1 Bolt 3/8"-16 Thread, 2 Relay Mount Screws. The red and black wires power the remote receiver in the relay and should always go to the positive and negative battery poles respectively. One side stud terminal of the relay goes to the negative pole on the battery, and the other gets the negative wire from the car
- REMINDER. This switch is to disconnect power directly from the battery, electronics that store data, like your radio, will lose memory. California users must keep the battery connected without activating the switch for several days before a smog test

First test & install went well with the exception of dropping the nut down into the horn (that was nice), but super easy to install. My battery has side posts so it is a difficult install from that perspective, I used the 2AWG cable & the side post adapter to attach to the (-) battery terminal. Connecting the negative lead is simple bolt & nut. It was re-attaching the (+) cable back to the terminal that is the major problem. (see edit below) The remote has a cover, so slide it down to reveal the ON / OFF buttons. ON reconnects the battery's circuit and you've got power. I like this disconnect style as it's either ON or OFF and the remote is super handy as you don't need to pop the hood. Edited 9/13: In order to install this I did need to buy a pair of 3/8" brass side post extenders. One for each terminal. The positive lead's bolt is too short to have anything sandwiched between the bolt and the battery's threads, so use one of the copper bars (you may need to bore one of the holes a tiny bit) to fasten to the positive's lead. Then you can attach your accessory positive wires (from the relay and I have a pig tail power plug) to the brass extender. Very simple and effective. I've had zero trouble with this disconnect. I'm very forgetful so it helped to make a wiring diagram of the positive & negative connections coming off the relay and back to your battery. **Word of Caution** when it came time to renew my tags it took me three trips to the emissions test facility to pass. With the disconnect engaged while not in use, it wipes the car's computer and the emission maps that they need to read. It took three weeks of driving with the disconnect off to finally pass emissions, so beware. I like this disconnect very much, it's worked well thus far.

I recently had my engine rebuilt and somehow, a gremlin has taken up residence in my car. It has been draining all the power from my battery, while it's not running. Since we got this sweet little kill switch, I simply turn it off, using the remote, each time I park the car for a while. An added benefit is that it is a theft deterrent. I will be taking the car to the dealer soon, so they can expel the pesky gremlin, but I may still keep the kill switch. I kinda like having the extra deterrent against and would be car thief.

Failed design, they certainly never tested this. DONT BUY IF YOU HAVE A C4 CORVETTE. NOT WORTH THE HASSLE, AND NO CONDIFENCE IT CAN HANDLE THE CURRENT DRAW OF A C4. MAJOR REENGINEERING NEEDED TO EVEN ATTEMPT AN INSTALLTION. The entire reason you would choose THIS product instead of one of the MANY kits that cost LESS THAN HALF is because you assume that this kit is engineered for versatile installation various different vehicles that use a SIDE POST BATTERY. Well, nope. 1) The screws to insert into the side-post battery terminal are WAY TOO LONG. A side post battery terminal connection has a very shallow depth before it bottoms out. The screw HAS to be short in order to tighten it down, or else the screw will bottom out. I had to use 4 LARGE WASHERS from my own parts bin just to "make this work" simply because they choose a screw length that COULD NOT POSSIBLY WORK. Thus, the first evidence that NO ONE FROM THE SELLER-MANUFACTURER ACTUALLY TRIED TO INSTALL THIS. And NO, I do not recommend stacking 4 large washers in-series with 100A+ of current! That just shows right away how poorly this kit was "designed". They just tossed in some cheap parts and gave no thought or testing at all as to whether something as basic as the battery screws WERE THE PROPER LENGTH. 2) No confidence that the relay is "better" (ie higher amp rating) than the cheap kits. THE RELAY LOOKS *IDENTICAL* TO *ALL* OF THE CHEAP KITS WHICH COST LESS-THAN-HALF-AS-MUCH, AND THOSE OTHER KITS ONLY RATE THEIR RELAY FOR 100A (500A startup). So this product's inflated rating for the relay seems highly suspicious in my opinion. 3) The ONLY thing that distinguishes this kit from THOSE THAT COST LESS THAN HALF AS MUCH are the two cheap copper jumpers. That's it. Apparently that is what they feel makes it a "side post battery" kit. Complete joke. 4) And those cheap copper jumpers certainly are NOT oriented in any way that can possibly allow a LOGICAL, NEAT, PRACTICAL installation of this unit unless you have a LOT OF ROOM in front of your battery, which is NOT THE SITUATION in many cars. Certainly NOT in a corvette, not as this kit is supplied. If they insisted upon using the same cheap relay module as everyone else seems to be using, instead of reengineering the relay to intelligently mount ON A SIDE POST BATTERY...then you would need a LARGE selection of copper brackets, twisted various shapes and sizes, to TRY to make this turkey fly. ...But turkeys cant fly ("WKRP" TV show reference....!) 5) Most laughable is that the red positive lead has NO WAY to be connected to the positive side-post battery terminal. The red ring connector is far to shallow to allow the car's side-mount positive connector to screw into the side-mount battery terminal. So again, THEY NEVER TESTED THIS OUT. Which means you AGAIN have to re-engineer it -- which in this case, means you will have to find another source for the +12V instead of at the Red battery post. Apparently this problem was overlooked because the design WOULD work with a TOP POST BATTERY. Thus, again, more evidence that this is just one of the cheap top-post-battery kits with 2 copper jumpers tossed into the box. ALL OF THE ABOVE DEFEATS THE PURPOSE OF BUYING A KIT THAT WAS **SUPPOSED** TO BE DESIGNED FOR A SIDE-POST BATTERY. In summary, the entire kit is just one of the cheap kits that costs less than half, and they threw in 2 copper strips. NOTHING ABOUT THIS KIT IS ENGINEERED FOR A SIDE-POST BATTERY except those hillbilly 2 copper strips. Totally flawed design, defective out of the box. Save your money. Junk.

The product works great, so far! The instructions are a little confusing and I realized that if the batteries in the Fab fail, I would not be able to start the car! I thought it was extremely important for the manufacturer to note which batteries are used in this unit, but the instructions only say that they are button batteries!
