My original relay did this and so does the new one that I bought.
As I read it it shows power from fuse box to the 3 prong harness, I don't understand why the single 18 orange has power as well- It's like the relay is getting powered twice?

I think whoever colored the wires used purple. Here is the uncolored version except for the orange wire.
The green wires would be for the compressor clutch switch which fed by the anti-dieseling relay and the yellow wire off the fan switch. It can work without the AD relay if you don't have one.\
I don't have AC on my truck so I'm not sure where it is if the truck has one.
I will search some threads and see if anyone knows.
Here you go.
