Not the status.

You want to come out of the flasher out into the 791-44. Use the Gnd and IR in terminals on the 791.

As far as where you put the 791, you can try to put it in the equipment rack (wire your dinky link or whatever into it as well) and use the emitter ports on the 791 to flash your components. This might work as long as the voltage drop on the run from the 6.4 isn't too bad.

If it dosen't work, you had it right before with the high ir out going into the 789, but still go into the Gnd and IR in (not the status).

You will need to use a meter to figure out which lead comming out of the 6.4 emitter port is IR and which is ground.

Hope this helps!
