If you want to jump start your car, connecting negative to negative and positive to positive is the only way to do it. Connecting negative to positive will result in extensive damages to the electric systems of both cars.
The correct order of colors to connect when jumping a car is red to positive () and black to negative (-).
Yes connect the positive first to the positive battery post, and then connect the negative ground to the engine somewhere and not to the battery.
When jumping a car, you should connect the red cable first.
Connect positive cable of donor battery to battery of car being jumped. Then connect negative cable to negative battery post on the donor car and lastly to a ground point on the car needing the jump start, normally the engine. Do not connect to negative post of battery needing a jump start. Let donor car run for about 5 minutes and then attempt to start. The instant the engine starts reverse the procedure to disconnect the jumper cables.
You connect the negative cable last and connect it to ground rather than to the negative post of the battery because there may be a small spark when you make the connection. Batteries can emit a slight amount of highly explosive hydrogen gas. That spark on the negative post can cause these fumes to ignite and explode. That is why you always connect the negative cable last and always connect it to ground and not to the battery itself as a safety measure.
When jumping two automotive batteries, connect the positive () cable to the positive terminal of the dead battery and the other end to the positive terminal of the live battery. Then, connect the negative (-) cable to the negative terminal of the live battery and the other end to a metal surface on the car with the dead battery, away from the battery.
