<p>PROBLEM SOLVED!! :) "So many trailer .light problems are due to a bad ground connection"--yes indeed!</p>
<p></p>
<p>The ground wire was disconnected between the 4-pin thingy on the trailer side, to the rest of it's wire--duh! moment. Everything does what it's supposed to now, so now I'm hooking up the markers and all will be finally ready to go!!</p>
<p>Thanks so much for all the help!</p>

<p>Thanks Lakota and Russ, I'll be looking at the white wires tomorrow. That may be the problem.</p>

<p>What Lakota said. From the various wiring problems I have fought I would start by making sure all the ground connections are good and that the trailer and tow vehicle are hooked together with a ground wire.</p>

Just a thought,,, possibly a reversed PARK/Running Light and Brake light.<br />
I should ask,, When park lights are on,, Are the trailer lights normal dim (light a running light) or Bright,(as if the Brake light is on )? This is NOT even pushing the brake pedal, Now on to suspiciaon number 2 , Are your trailer lights on a COMMON WHITE ground? And is the White grounded to the trailer AND the plug?<br />
<br />
I bring these to common problems up because the original grounds (white) on the trailer where corroded,,…

<br />
I bring these to common problems up because the original grounds (white) on the trailer where corroded,, and the white wire on the pigtail plug in (white) was also corroded where it attached to the trailer..<br />
I always carry those magnetic lights from Harbor freight for testing the pig tail off the vehicle to make sure the wiring to the plug was correct if I came across an issue (s) as you are having.. So called my $10 trailer Test light kit.
