Rewiring gooseneck to truck 7 pin connector

[JohndeereG]

I have 12K Diamondback gooser that has the smaller 4-5 pin plug that was used on a earlier truck. I want to use the factory 7 pin plug at the bumper.



I currently have a complete plug/wire harness that was removed from another trailer which will work in the truck's factor plug. I need to splice this harness into the trailers wire harness. What I am looking for is a diagram identifing the pin configuration for a 03. I did a search and found a couple good links but I just need to make sure that these are fairly universal as far as pin placement/use.



Thanks in advance.

The 7-pin Pollock/Bargman connector terminal designations are, as far as I have seen, very standardized. The same cannot be said for the 6-pin connector wiring used on many goosenecks. Here's a handy reference (note that you can click to get 6 pin wiring):
