Trailer Wiring Issue

[Will!]

2005 Silverado 1500

So I attempted to use my trailer wiring this weekend but ran into a few issues.

 

I had to splice back in the female end to the connector on the receiver. All of the wires matched except white on the end I was splicing to the oem harness, but according to the owners manual white is ground though the truck has a black (I'm assuming ground since all others matched and wire is the same gauge) I was not getting and lights on the trailer. I tested to see if the prongs were getting any power, the only prong that had power was the (yellow) left turn and stop.

 

I checked all the fuses and had a few that were blown, replaced all of them today and now I am not getting power (according to the plug in tester) to any of the prongs now.

 

What gives? This is the first time I have attempted to use the trailer wiring in several years.

Is the actual trailer wiring in good working order? Try to connect the trailer to another truck if possible.

 

I may have missed it but what was the reason you had to cut wires from your factory harness? That should not have to happen.
