It's very common to put the shunt in the negative wire battery connection, But in most cases it is not absolutely necessary,
The shunt is just a measuring point, away to measure amps via a calibrated voltage drop, example 0.01v drop equal 0.01 amps on the meter,
Negative is used most often , mainly because there are usually less connections on the negative post, so usually only one main negative wire has to be moved from battery to shunt, the vehicle frame is the negative BUSS BAR for most wiring, most meters using stunts will work just fine, no problems, connected to the positive post, you just have more wires to move and connect to the other end of the shunt.
I have done this with no problems, when the negative post had clearance problems for mounting a shunt
