AC compressor wiring and custom low pressure line

92 s13 / redtop

I'm trying to get my ac all hooked up and I realized that there was no plug or harness to plug into my compressor. I did some searching and realized there should be a single wire plug that comes from the relay box behind the drivers headlight. I look under the box and see that theres a group of wires that has been hacked and taped up. Removed the tape and see this.




To my understanding, it should be the blue w/ green stripe wire that goes from the relay to the compressor. Here, it looks like the blue/green wire coming from the relay is connected to a blue/green wire coming from the rest of the body harness. But then its just cut off, right there are the connection. Are these two wires supposed to be connected together into a single wire that then plugs into the compressor? How should I go about this?

Secondly, I think I need to get a custom low pressure hose made because the service port interferes with my turbo intake. I've read of people bending the hard tube and hose muffler for clearance but that simply isnt working for me. I went to look into getting a custom hose made and he quoted me ~$200, saying there needed to be multiple connections to incorporate the displaced service port. He asked me to find someone with a custom line and bring him back some pictures to see how others have been going about it. Anyone have any suggestions and pictures on best way to go about getting this custom line made? Pictures would be awesome! I've been searching for a couple months now and havent come across any pics of others' custom lines.
