Computer grounds are either negative or positive grounds. Usually, there is an electronic diagramed indicator near the charging plug-in point. I should think most of them are negative ground. You have to go by the schematic designation. If you don't know or don't have a schematic, call the mfg maker and ask them for your particular model whether it is negitive ground or positive ground. (Caution:You do not want to reverse these grounds). Either way, if you do reverse them, you will have melt down instantly.
Give you names of computer retails shops?
I believe the computer controls the grounds,not the positive.Therefore the injectors are"live"when the key is on,but don't fire till the computer grounds them.
