BAGE 14AWG SAE Connector DC Power Extension Cable Quick Disconnect Plug Cable, for Motorcycles, Cars, Tractors, Solar Panel (4 Pack -30 cm/ 1ft)

These are very nice, good quality connectors at a decent (for 2022) price. Packaged in a nice little zipper plastic bag; showed up in a day or two without Prime. Some comments are saying they are "reverse polarity" because the RED WIRE (positive) is on the PIN side (aka "male") and the BLACK WIRE (negative) is on the SOCKET (aka "female"). But the description clearly states: "This cable designed for extension cable for battery charger and devices with sae connectors." IT IS a pigtail you can use to PLUG INTO a mating connector that has the power supply already on it with the proper orientation, with RED/FEMALE/POSITIVE and BLACK/MALE/NEGATIVE and this plug will keep red/positive and black/negative on the wires or "pigtail" for you - which is cool. If you plug two of these into each other, red and black will be swapped - that is the nature of these plugs and you must be careful. Likewise, if you connect two of these together using red-to-red and black-to-black, when you plug one end into a properly oriented power supply - socket/female/positive - your patch cable now has a HOT/POSITIVE/MALE/PIN on the other end flopping around that can short out - YOU NEVER WANT THIS on a negative ground system. On a negative ground 12 volt DC system (typical USA cars, motorcycles, RVs, ATVs, boats, etc.) this pigtail is NOT INTENDED to be connected to a power source (eg the battery, power supply, charger, etc. on the wire or "pigtail" end); YOU CAN IF YOU WANT TO, but you would want to put BLACK/FEMALE/SOCKET on (+ POSITIVE), and RED/MALE/PIN on (- NEGATIVE) and now it APPEARS you have a "reverse polarity" situation, based strictly on color code at this connector! Ok... look... forget about wire color for a minute... pretend BOTH wires were gray - the POWER FEEDING SIDE of any connector, no matter how many extensions it has or plugs it goes through (any plug coming from a power source - battery, power supply, charger, etc.) on a negative-ground system should ALWAYS have the POSITIVE (+) wire on the SOCKET/FEMALE and NEGATIVE (-) on the PIN/MALE... no matter what. Period. In electrical, we call the HOT/POWER side the "LINE SIDE" and "DEAD" side (that you want powered) the LOAD SIDE. YOU ALWAY PLUG A LOAD SIDE (MALE/PIN) into a (POWERED) LINE SIDE (FEMALE/SOCKET). THINK OF IT THIS WAY... do you want any live "hot/positive" wires on a bare, exposed pin you can easily touch with your fingers, or would you prefer it to be recessed in a socket (female)? (Think of what you do when you plug multiple extension cords into each other in a single wall socket... blades (male) go in the wall (female)... other end is now "hot" and "female" and you plug another cord (blades) into the hot end (socket)... and so on. You are never exposed to "hot blades" you can touch with your fingers on a household extension cord. But one end has only blades and the other end has only "holes." With these auto plugs you only have only one plug for EVERYTHING and it has one of each to mate to another - one pin and one socket. That's the issue.) With these connectors, because you have one male and one female on each plug, the advantage is you only need one "type" of connector and you don't have to buy males and females like you would if you were building household extension cords. The DISADVANTAGE with these is, if you strictly go along thinking wire color is always "RED=POSITIVE" and "BLACK=NEGATIVE," you may end up with a "hot (+Positive) male/pin" flopping around and if it touches anything metal on a negative ground vehicle, it will arc and spark and blow the fuse... and you will be sad. (You DID PROPERLY FUSE your POSITIVE SIDE supply at the source, right?) If you use this connector (as it is intended) to plug into an EXISTING, properly powered mating connector with RED/SOCKET/POSITIVE (such as a "Battery Tender" will have) and BLACK/PIN/NEGATIVE, the PIGTAIL (i.e. wires) on this plug that you are wiring to feed a device will KEEP the RED on POSITIVE and BLACK on NEGATIVE for you! That' why some think it is "reversed"... because they are trying to use it as the power ("line") side of a circuit. So these are kind of cool because NORMALLY, when you use these things from the auto store, every time you plug one in to another one (like an extension you made), you are swapping the color: red becomes black and black becomes red from the socket's perspective. WHEN YOU USE these connectors, you MUST ALWAYS keep track of where the POSITIVE and NEGATIVE is no matter the wire color... (learn to use a volt meter on DC volts setting and how to identify the positive and negative leads) and YOU MUST ensure you do not end up with a "HOT PIN/MALE/POSITIVE" flopping around that could touch vehicle metal. I always focus on keeping the (+) POSITIVE protected by the female/socket side and ignore color when working with a bunch of these. It can get confusing, especially when tired and trying to configure something different on the road using wire nuts, stripping wire, without a volt meter. ALSO, if you have one of these on your motorcycle, car, ATV, boat, etc. (coming from the battery with RED/HOT/+/POSITIVE on the socket) you should have the protective cap for it to keep dirt and water out. BTW, these are GREAT for "heated gear" on the motorcycle because if you forget to unplug when you get off, they will usually pull apart without any damage to the wires or connector... if the connector is on the dismount side - like, the left side of the seat if you get off that way. Again, make sure it is FUSED properly!! If you used a threaded connector, you'd pull out wires (or fall down when you get to the end of the cord like a dog on a chain) and possibly short something out if the wires pull out... and blow that fuse I know you have. For my motorcycle, I have a freezer zip bag full of these made up to power and charge everything 12 VDC, including extensions that swap red and black. Most useful is the one on a cigarette socket which powers anything with a cig. plug and even use a dual USB plug that goes in the socket for charging the phone and GoPro batteries. Sometimes, I keep track of "power side" by using a sliver Sharpie and I'll mark the edge of the (black) connector silver that is negative if it is "swapped" on a red wire - so I don't get confused. You can use wire tags, colored tape, colored zip ties, and do the same to keep track of any "color swaps" at the plug itself. (I really wish both wires were "gray.") Just remember to NEVER LEAVE (+) POSITIVE on the MALE/PIN side flopping around or even if it has a cap because when you take the cap off, if it slips out of your hand it may short on something metal... and blow the fuse. Keep spare, properly sized fuses handy, while you're at it. You'll probably need them! DO NOT FUSE larger than the capacity of the wire or you may melt the wire before the fuse blows - and even potentially cause a fire which is bad under a gas tank where most recreational vehicles put their batteries! I have witnessed this on a motorcycle! It's pretty scary. (Luckily, they got it out with a fire extinguisher before it lit the gas tank.) AS ALWAYS, IF YOU ARE NOT comfortable working with electrical power, get help from someone who is! Don't mess with it if you are not sure. Hope this helps.

100% simple to wire my WildCat XX

I purchased these for part of my battery box project. I have one set hooked to the battery and the other connected to my fish finder. I did have to reverse the wiring since thy are all the same and you cannot connect the cords together as they reverse the polarity. Not an issue but make sure you purchase the plug for it to make it easier for connections. I’ll end up updating this on my battery box.

These are better quality than what I expected. The wire is sturdy, not flimsy. The connector makes a very strong connection with my other SAE plugs. My brother-in-law and I have both used these successfully. I ordered another set of 4 after receiving the first set.

Like to use this hook up for making quick connects on my 12 volt setups on my homestead.

These are great if you have one battery maintainer that you switch from battery to battery, these make it easy.

Nice high quality, with plenty of current capacity.

Work well for my lighting project on the corvette
