I bought the electrical probe tester. i determined that the issue is not in the tow vehicle side. I haven't gotten to testing the line on the trailer side. I am thinkign that the idea would be to test from one point in the overall connection to the next...so next i should see if I have pwer and ground at the trailer side plug in, and if yes i should test if i have power and ground on the lights individually. sound right?
Question how do I knwo if the problem is the ground 9and i understand this is most likely the problem) or the power?
thanks as always!

I'm assuming you have three-wire or push-in stop/turn/taillights and properly grounded those with the hire. Just curious - and certainly not trying to insult your intelligence! - but how did you ground the sidemarker lights? I think those usually ground through the mounting stud or there's a little metal clip on the backside through which you screw one of the mounting screws.
Of course, that doesn't explain why NONE of the lights are working ... if only the side marker lights were improperly grounded, the rear lights should still work
Wait a minute ... did you run a common ground wire and just splice jumper wires to each light, or did you run a separate ground wire for each light? So a total of four wires rather than one?

You bought a test light not a meter right?
Your wires have an open in them somewhere. I would check any junctions.
Especially where you installed the light itself. Pull the light and check at
that location for power, before the light, to the trailer as a ground.
PS...
A wire could have scraped against something and grounded itself to the frame Or
It can also be bad wire.

There are two possible scenarios,... One, bring there is problem with fixture... Two, there is problem with power from tow vehicle, meaning if the power to light trailer lamps comes through a "converter" the converter may be bad because it can not supply enough voltage (power) to light the actual fixture lamps ( probe takes very little power to light lamp) ... Since Both side have same result with the testing I would be suspicious of there being bad converter in tow vehicle if there is one or there is some confusion on how lamp fixture is wired.... Are by chance new lamps LED, if the are they are very specific how they are wired or they do not work....
