I am retarded at everything when it comes to anything on my car. My question is...How do I properly install a rebuilt ECU? I know I have to plug it back in, but I read on the forum that it has to be grounded or it can screw everything up. Would I connect the battery first or after it's plugged? What's grounding? I really need to know because I've pretty much never did anything on my own cars except for an oil change and DSM is pretty much a new language to me. Thanks in advance.
 
just unhook the positive terminal on the battery then install the ecu plugs, pretty simple, then hook the battery back up and your car should run if u did everything right
