Proper way to disconnect battery neg first neg last

I was told by someone with mechanical ability.
Being that these motorcycles ATV's side by sides have sensitive brains , ECM's etc...
The safest was to disconnect a battery is to disconnect the negative first and when connecting the battery to hook up the negative last.
Please let's hear your ideas.

Polaris Pulse 6 Busbar

Hi,

Has anyone had any experience with the Polaris Roof 6 Busbar accessory? I installed mine and I was expecting the same operation as the one under the hood (from the factory). Much to my disappointment, all I'm getting is switched +12V, no constant power. Considering it has hookups for ACC, GND, and +12V I'm hoping I'm missing something....

Can anyone share their results?

Thanks,

Bill
