GPS tracker ''hardwire'' adapter to battery

[ko5i]

Hi guys.
I have question i had this gps tracker ''TK102 nano'' its been doing good for past 5 months but im tired of constantly switching the batteries inside of it .
So i bought this ''102 NANO GPS TRACKER HARD WIRE CHARGER KIT VEHICLE BATTERY ADAPTER TK102 FOR CAR''
On ebay, basically adapter i connect the gps to and then from adapter i connect the cables to battery.
But the question is should i just connect to battery ? Like positive to positive negative to negative ? , because i heard somewhere that when connecting something on your bike something new that will constantly take power best to have some type of fuse or connect not straight to battery but to fuse box ?
Whats your opinion guys?

Thanks !

Connect it to a switched live. I've used one of these, it'll flatten your battery if left always when you leave the bike for a few days.

There wasnt any instruction with this hardwire kit for gps :/
So basically i just connect the ''red'' cable which should be positive to cable switch on my bike, and the neutral cable which probably is blue because no other cable i connect to negative/neutral on my bike [which is basically like earth because neutral/negative is connected to frame or something from what i remember
