Thanks for the responses... I have looked at both of my Rangers ( 97 an 98 ) and neither has the 'pig tail plug" ... there is a plug but it seems to connect only the two harnesses, ie: the main harness running to the back and the "left /right " mini-harness under the bumper that provides all the wiring to lights etc...
I decided to take the bull by the horns and jump into the tail lights and it has really turned out MUCH easier than I thought. I used my VOM to identify the power leads to the Tail Light and each Directional, 'vampired' in leads from each ( total 3 ) and soldered them to the proper hitch-plug leads, used shrink sleeves to insulate and then bundled all together.... WOW it works !!
Just wish these little trailers had a Brake Light system... but Running lights, Marker lights, and Directionals is good enough to get to the dump and back !!
Thanks again guys... drive safe Wherever you are...// Ernie in NH
