Narrative:

Had an inboard log 1 for status message. 'Right reverser is low valve.' I started to pull up paperwork to do the job. I pulled up the 'service tip' for EICAS message reference 'reverser is low valve.' I looked at paperwork and called maintenance control, talked with engine desk. I told him what I had, also said there wasn't an MEL reference for that EICAS message, so we both talked about how I could make a deferral so we wouldn't lose the trip. So we came up with to inoperative the right engine reverse and what MEL reference to use came up with 'thrust reverser interlock actuator' inoperative. I pulled up the MEL card was MEL #7834C. So mr X and I started to inoperative the right engine thrust reverser. The MEL was very hard to understand. So I did it step-by-step, when came to disconnecting the rod end. So I had mr X move the right engine thrust reverser handle. The rod end that moved I disconnected it, then dispatched the trip flight to lax. Maintenance called and told me aircraft came back and it was at YYY, and found out that the wrong rod end was disconnected. So I reconnected the rod end back to airworthy condition, and found the right rod end, so I disconnected safety the rod end off and cannon plug, made write-ups, had items inspected.
