You probably don't want to know.
This is the part where if I were a salesman, I would wave my hands in front of your face to distract you from the price.
I mean the injector connectors are going to be $5 per, then the plug is going to be about $15 with pins, so that's $35 plus shipping, so $50 is the number I would say. Wish it were less, but I can tell you it was easily double that much for what I've done in my car. Every part of my harness is covered in woven fire proof loom with heat shrink tubing where necessary. If we are both at SDAC or an event I'll give you the details. Like I said, it's an investment but it will last for a long time and the great thing with the stuff I am using (Molex) is that everything is interchangeable. So if I decide to move wires around or if I need to increase the number of wires going through a plug, I just upgrade the number of wires the plug will hold.
I did call the place where I got them listed up top in this thread and asked them about bulk discount pricing. If I can get some interests, I may make them and be able to save some on the connectors, but I don't think they will come off the price that much. The connectors though, man I would upgrade those in a heartbeat. They use a clip that only needs to be depressed to remove the plug from the injector. I could disassemble that area in a matter of minutes if I needed to. Makes working on the car very easy.
Thanks for the comments, btw. I've done some upgrades and it looks a little better now, need to take some pictures. Last thing I'm going to do before I work on the fuse box is relocate the MAP to the area where the wipers are.
