Review: 取り付け跡が有り全体に変色汚れの有るのが届きました。 多少の取り付け跡なら使おうと思いましたが、錆汚れも有り数年使用された感じの製品で返品依頼し送りましたがそれっきり何の応答も有りません。まさかその様な対応に成るとは思ってなかったので製品の画像も撮影していませんでした。真摯な対応が有れば評価変えます。とても残念です。 追記 返品手続き完了し返金が有りました。desertcartの返金手続きが少々分かりにくい所が有ります。 製品は良い物なので製品管理を慎重にして頂く事を願います。

## Questions & Answers

**Q: Will this work on a c5 corvette ?**
A: Well, yes but. It's REALLY tight in there, up against the fuse box. Figure on cursing and scraped knuckles. You can't swing a wrench and a socket won't fit in there. I pulled the battery loose, first attached the - cable to the switch, then attached using the long bolt and my fingers. Finished up with a very short wrench from my toolbox. A real pain but the switch seems to work well and makes disconnecting a breeze.

**Q: Why does it have to be connected to the negative terminal and not the positive terminal?**
A: That's ok, positive or negative can be connected.
We recommend to install this cut off switches on the negative, not the positive, because lower current in negative, will be more safety. 
The switch can be install in the negative/positive  wire, another short battery cable or cut existing cable and attach terminals on each end.

**Q: Will this fit a duralast gold 101-dlg? cadillac 2007 sts.**
A: i bought it for 1977 corvette and it fit I am sure it will fit your sts.

**Q: Does this disconnect work on newer model cars**
A: 1. you will need about a 3" space next to the negative terminal in order to have room to install this switch.  2. depending on the vehicle you will need clearance for the "knife" to be up in order to close the hood, or it could be installed so it opens to the side if there is enough room there.  3. disconnecting the battery may require radio code for the radio to operate again after removing the power.  Other functions may be affected too like the clock, possibly other functions as well  4. you will need the proper tool to tighten the bolt to the battery otherwise it will move about as you operate the switch. I am using this on a full size chevy snow plow yard truck (off road only) with plenty of room and I don't need the clock, that one does not need radio codes after disconnection.  Look at the pictures carefully to decide if it will fit on your vehicle, if it fits, it will work.
