Not a TriMetric, but for $20 might be worth trying out...
Bayite DC 6.5V-100V Digital ammeter voltmeter Amazon suggested this for me and I'm thinking for $20 I might just give it a try. Has very good reviews too.

12v B+
Neg
And one twisted pair for the shunt sense amp reading wires
The B+ neg aka power wires can be twisted or separate stands
So for your question two twisted pairs
