Tether between Lionel F-3 AA units?

Contact Chuck Sartor at O'nly 3-Rail and pick up some MTH diesel tethers.  They have 10 leads in a nice compact package.  Some of them are heavier for power and motors, others are small for lights and the like.  $18/set for the male/female combo.  These are straight tethers and look great between diesel units.  

I just used one of these to do a PS/2 conversion for a pair of Williams A-A Reading units.

As far as feeding the tether through the shells, for the powered engine, I mounted the connector behind the door and cut out a neat square hole the size if the connector.  It's recessed so that the shell doesn't hit it, I made a 90 degree bracket to hold the connector.

For the trailing unit, I just notched the frame and shell enough for the cord to come out, similar to the way most steamer tethers are done.

I always use connectors from the R/C car and airplane section of the hobby shop. They are small, but have large pins and recepticals. They work great.

Roy, do you find small connectors with 8-10 wires that are suitable?  How about the hood for the tether cord?  Got any specific references?

I found some 5-pin connectors at AllElectronics. They are a good size.

I looked at some of the Molex connectors but did not want to have to crimp pins.

These were complete with pigtails.

I will post pics when I can.

Those Molex connectors are a bunch larger than the MTH tether, that's why I went for the tether.
