Going single FD can i reuse stock harness?
Ok so Im going single turbo on my fd. I was wondering if i can just disconnect the rat nest from the solenoid and not cut them or rewire them (leaving the plugs there only)? Will the car be fine like that?
Thanks in advance.

Yeah you should be fine. PFC doesn't care about the emissions solenoids or sequential solenoids since your turning that off.
That's assuming you're using a PFC but it shouldn't matter which standalone. Ideally you want to remove those wires because they just get in the way though. It will clean things up tremendously.

You can leave them there but In my opinion that is sloppy. I open up the harness and remove everything that is not used. Makes for a much cleaner engine bay. You have to be careful as some of the connectors share power so you have to open it up and see where the wires go. The idle air control valve for one, shares power with the gray solenoid connector. At minimum you should bundle up and tape the unused connectors if you don't want to modify the harness. If you need help I can do it for you.

You can certainly reuse the stock wiring harness, but there are some things you want to keep in mind. Assuming the harness has never been replaced (most likely it hasn't), then most of those wires and connectors are going to be very brittle due to age and heat. Depending upon which injectors you decide to upgrade to, with your build, you're going to need to solder/splice in pigtails. That can be a real pita if you're working with a brittle harness. Also, when it comes time to troubleshoot problems with your build, having a clean engine bay that's free of unnecessary parts/connectors/etc. can save you a lot of time and headaches.
Long story short, make sure you do it right. I think everyone here who has completed, or is in the process of a build, looks back and thinks "man, I would have done so many things differently". Follow the link posted above and remove or tape off those unused connectors. While you're doing it, if you notice any damage or that the harness is unserviceable, then you should start with a fresh harness. I've provided a link to a very good alternative, assuming you have the cash. It's what I used and I am very glad that I chose that route. Good luck with the build, and keep everyone up to date!
