Narrative:
During usb (upper side band) mods; there is a chance I could have routed usb wires onto or near fqis (fuel quantity and indication system) bundle on the right side run to first officer in the east&east (electronic and equipment) to the forward wheel well. I was not aware of the fqis wire bundle location and could have routed wires with the improper clearance and or sleeving. I realized I could have made the error when I read the current usb mod task card which stated look for fqis bundle and make sure the proper clearance is used when running the right side.
