Would wires made of anti-matter have the same electrical properties?

Would the right hand rule still apply or would it be the left hand rule? Would electricity be propagated with positrons and would this change how the magnetic fields would be generated? 

Is it the same, but opposite or the same in general?

All the same rules and formulas would still apply;  with the definitions we use, a current going in a given direction can be the flow of positive charges in that same direction, or a flow of negative charges in the opposite direction.  Or both!   Magnetic fields are the same for the flow of a positively charged antiparticle (like a positron) as for a positively charged particle (like a proton).  But, like you suggested, in an antimatter wire the moving charge carriers would be the positively-charged positrons, with the anti-nucleons forming the fixed "lattice" of the solid wire.

Slight aside:  there are a variety of sign and handedness conventions baked in to our laws of E&M.  The sign of charges, the direction of current, the direction of magnetic field, and whether to use the left or right hand rule are some of those.  The choices that we use are largely due to choices made by people muddling in the dark trying to figure things out as they went along (like Ben Franklin assigning positive and negative charge).  The physical observables of course don't care what choices for those we make, as long as we're consistent.

Note that we do have experience with "antimatter currents" in the proton-antiproton and electron-positron beams at various particle accelerators.  We also have experience with the flow of positive and negative charges in electrolyte solutions and plasmas.  We of course don't have experience building solid antimatter wires;  connecting those to our instruments (or even suspending them magically in a pretty good vacuum) would be... a bit too exciting.
