A system for delivering a cable through a tubing string to a downhole location in a well, includes a plug and a receiver. The plug includes a first connector configured to be operably connected to the cable and further includes a plug housing adapted to fit within the tubing string. A check valve operably associated with a passage in the plug housing restricts fluid flow through the passage in a downhole direction and allows fluid flow through the passage in an uphole direction. The receiver is configured to be positioned at the downhole location and includes a receiver housing and a second connector configured to be operably connected to a downhole device. The second connector is adapted to communicate with the first connector when the receiver and plug housings are engaged.
