This is a detailed review. I was very apprehensive about changing my battery and did considerable research prior to making the decision to purchase this cable and do it myself. Hopefully this will provide the necessary information to help others make an informed decision since some of the reviews on the Amazon web site mention incorrect wiring issues with this connector. During my use, I did not discover any wiring issues when using on my 2011 Nissan Murano and the cable worked as advertised. I cannot give advice as to wiring issues with any other vehicle but if it works on one OBD II vehicle it logically should work with all OBD II vehicles but just be aware there may be exceptions.Highly recommended. I used this cable on my 2011 Nissan Murano when I installed a new battery. My battery was not giving me any problems but, since it was 8 years old, I decided to replace it before winter set in as a precaution. Since I had was not in a hurry, I checked the service manual for my particular model and found out that a memory/setting saver device was recommended when changing the battery. According to the Nissan service manual, if the battery is disconnected without having an external source of power to maintain memory and settings, there is a multitude of items that would have to be initialized (not automatically reset to factory defaults) through specific reset processes including the accelerator pedal released position learning, throttle valve closed position learning, idle air volume learning, power window switch, sunroof switch, automatic back door, power seat memory settings, entertainment system settings, air conditioning system settings on some models, etc. You get the idea, this could easily turn into a major project if you did not save the memory and settings.My first inclination due to the complexity of the reset process, if a memory/settings saver was not used, was to have my battery installed by a professional 3rd party installer or the dealer. In trying to decide on who to do it, I called several places including 2 dealers (neither of which used a memory/settings saver). I found only one 3rd party installer that used a settings/memory saver but they did not tell me what type so I was not totally comfortable with them Most of the rest said that there no problem with changing out the battery without an external power supply since they had had no reported issues doing it that way other than having to reset the radio presets on the vehicles they had done. One installer even said that they left the engine running during the battery change out process so that memory/settings were maintained (not a good option in my opinion). I was not comfortable with any of these options so I decided to buy a settings/memory saver cable and do the job myself according to the maintenance manual. Apparently, the local dealers did not read the manual or they possibly went through the cumbersome initialization process and manual reset process since neither of them used a memory or settings saver. I wanted the job done correctly so I wouldn’t have the possibility of any gremlins running around in my electronic control systems, etc. that I would have to deal with later or have to redo a bunch of settings.After considerable research, I determined that the VSTM Cable was the best choice for my application since it is hooked up to the OBD II port. Some memory/setting savers plug into the cigarette lighter outlet of the car that the battery is being changed in. On the Murano the cigarette lighter outlet is not live when the car is off and I didn’t want to energize any additional electrical systems by leaving the car in the accessory or on position while I was disconnecting the battery so the memory/settings saver would work. My decision to buy the VSTM Cable was a good decision. The cable worked flawlessly with the car turned off so minimal electrical systems were energized during the change out process.After I completed my battery replacement, all of the settings that I could check were functioning properly. Idle was at spec and acceleration was as smooth as before the battery was replaced (no drivability issues), windows worked properly, memory seats worked properly and settings for the entertainment system, phone, trip odometers, gas mileage history, maintenance settings, etc. were all maintained.There are a lot of videos on YouTube that will show you the mechanics of changing your battery on your specific vehicle and I recommend watching a few if you have the time just so you don’t get any surprises whether you do it yourself or have an installer do it so you will know which questions to ask.A word of caution, if you do change the battery yourself and use a memory/settings saver, you will need to make sure that the positive cable is insulated from touching any metal that would ground it out while the memory/settings saver is hooked up. The positive cable will have voltage running to it and if you should accidentally ground it, it could damage one or more of your electrical systems or blow some fuses. As a precaution, I wrapped mine in a garage towel and tucked it safely out of the way during the battery removal/replacement process.Your particular vehicle may not be as complex as mine but my recommendation is that, if possible, you should do a little research before having your battery replaced either by a professional installer or yourself. If I had not taken the time, my results might not have been as positive and some additional effort or expense might have been required to resolve the issues that could have possibly resulted from lost memory and settings. However, in all fairness, maybe the battery could have been removed without a memory/settings saver and not created any problems other than resetting radio presets as several installers advised me. But for me, I was not willing to take the chance. Buying the VSTM Cable and doing the job myself according to Nissan service manual recommendations to use a memory/settings saver gave me peace of mind that the job was going to be done right and save me any aggravation.In summary, I would highly recommend the use of the VSTM Cable since it is very easy to use, is well made, allows the use of a cigarette lighter plug or battery clamps for your power source, and is long enough to stretch between two vehicles and still allow you enough room to open the doors to attach the cable ends if you use the cigarette lighter adapter.It is also worth noting that when I contacted the supplier via the Amazon website about some of my concerns and questions about the cable, they provided excellent customer service, responding very quickly and providing me with the detailed information that I needed.

Excellent tools. Fast delivery

I needed to change the battery in my SUV and purchased this device to avoid losing the radio and vehicle engine computer settings. The device arrived in a plastic bag with no instructions, but it wasn't too hard to figure out how to use it from browsing some online videos. The device appears to be sturdy and well made. Of course, you need to connect the device and provide a power source before disconnecting the battery. (For a power source, I used a portable "power block" that I use for camping and emergency power, but you could use another car battery as the device comes with clips to connect to a battery.) To make the connection you will need to locate the OBD-II port under the dash (again the location of the port for your vehicle can be found online). The OBD-II port and plug on the device are shaped so that they only fit together one way. You don't need to be concerned about plugging the device in upside down. It took some pressure to push the device plug into the port and I was worried about pushing too hard and damaging something. However, I was able to reach under the dash and hold the back of the OBD-II port while attaching it. My power block has a female cigarette lighter port and the device plugged into that. The device plug has a red LED light which comes on when a good connection is made. The only problem that I had was that it took several minutes to make a good connection with the power block. The LED light would not come on and I made several trips back under the dash to the OBD-II port to unplug and plug in the device. After deciding that the OBD-II port connection was good, I focused on the connection to the power block. The cigarette lighter plug was fully pushed into the power block but the LED did not light up until I rotated/twisted the plug which seemed to make the connection. My understanding is that the LED indicates that the device is properly connected and power is flowing. Once the red LED came on, it stayed on through the entire process. When I disconnected the vehicle battery, I got called away before installing the new one, and it was about an hour and a half before the new battery was installed and connected. Once the new battery was installed and the device was disconnected, the radio still functioned and no radio presets were lost. I have no way of checking the vehicle computer system settings, but the vehicle appears to run well. I had a very good experience using the device and would recommend it to anyone needing to change the battery in a car.

Easy to use and long cables that reach my other car battery for power.
