An air carrier inspector; reports finding a left-hand main landing gear (medium large transport) anti-skid system electrical wiring harness to the wheel spin transducers cross-wired in the axles. Outboard (O/B) harness routed to inboard (I/B) and I/B to O/B. He was performing a receiving inspection of the A320 medium large transport from a contract repair station overhaul vendor.

Narrative:
Contract repair station vendor overhauls all landing gear assemblies for 'time' gear change [for our air carrier]. Receiving inspection required of all components. One task requires confirmation of main landing gear (medium large transport) wiring harness routing in the axles. Found the left-hand (l-h) medium large transport wiring incorrect. Outboard (O/B) harness routed to inboard (I/B) and I/B routed to O/B position. This wiring concerns the anti-skid transducers. See maintenance write-up for corrective action. Vendor repaired part.
