Since I am planning on going single turbo, it looks like I can delete the rat box. This means I'm going to have a bunch of connectors that don't go to anything. Do you de pin your wires and cut open the loom to remove the wires? Or do you leave the connectors in place, cap off the plugs and send it. Just not sure if disturbing the harness too much is a wonderful idea.
just want to make sure there is also no issues deleting the box, correct? The only thing I was unsure of was the "port air control solenoid". I assume it's sequential related? I attached the diagram for those who are unfamiliar with the what solenoids are on the box, specifically. I also found this diagram on another forum so maybe it may benefit someone else.
Edit to add, car will be on haltech 1500
I removed the engine harness from my car when I installed different fuel injectors (which needed different connectors), added a fuel pressure sensor, and removed some of the original solenoids from the engine bay. But if you're just removing solenoids I would be tempted to just cover the connectors and leave the harness alone. Don't cut any of the connectors off, some of the important 12V supply wires are daisy-chained and things like the boost control solenoid or idle air control solenoid might stop working if you cut off certain certain emissions or sequential control connectors.
I'm still twinning, but no emissions. What I didn't need anymore, I wrapped with heat resistant fiberglass tape, then over-wrapoed that with TESA tape. Cinch secure with heat-resistant zip ties or wire. I also vote not chopping up harnesses. Eventually, I'll go single and will either buy a Rywire harness or do more of what I already did.
Doing anything with the unused connectors is entirely optional. You can simply leave them be. The ideal solution if not replacing the harness is to open it and de pin the unused wires and remove it all the way back to the ecu. It really doesn't matter, it's entirely for presentation.
Best approach is to replace the harness entirely. Rywire is our go to
