Thanks for the help guys, I got them in and they look really nice.

 

Here are the instructions from www.uprproducts.com I'd imagine they are the same.

I had the same problem. I just got this gauge insert last week with no instructions. I have found the sites showing how to put them in but I have seen nothing about how to connect the wiring harnesses or how to change the color.
