Mine arrive tomorrow!

I placed three 0.0188" diameter holes in each brake beam and and through the bolster.  The brake beam holes are 0.034" above the holes in the bolster, so you'll need to bend the wires if using a single piece of wire from beam to bolster to beam.  I'd do that with a jig.   The top of the axle is 0.09" above the brake beam holes, if you want to run the wire over the axles.  The brake beams should be about 1.2" apart (and the brake beam holes are 0.03" deep)

An alternative would be to use a pair of 0.018" wires which are 1.2~1.3" long, running from beam to beam, connected via jig drill brackets to other wires passing through the bolster...which could allow for the brake beams to be readily removed.

Note: these holes also allow the use of wipers for power pickup or to secure a contact or such (per Jim's interest in power pickup).
