DTR as aTugger
When the DTR is converted to a tugger
It can be then clipped to a harness. The DTR converts to a tugger in less then a minute.
I Just remove the elastic and slide the push rod and plate assembly out of the bell and
attach the small tugging clip rod as shown.
This is the chest harness. Its very comfortable and easy to make.
Its made from 1 inch elastic strap and 3/4 inch web strap.
1 keying and
I use surgical tubing cut in half for the tension band.
this is when I'm using it just as a tugger.

( Nighttime tugging while sleeping can be dangerous 
Doing so could damage the skin tissue from lack of  circulation due to night time erections.
Unless you have extra skin I would not even attempt this. Even still do so at your own risk!

  You can make a leg harness easily with elastic strap and a leg support.
This is the way I started my restoration process.
