Single turbo harness on parallel turbos?

Curious if I could just run the single turbine harnesses I'm finding online. I have done a rats nest delete, all that, but I'm running a factory harness that's a little beat. Was wondering if I can run the single turbo harness if I'm running my turbos parallel instead.

A new harness for a single turbo will most likely have none of the emissions connectors or any of the connectors for the solenoids to control the turbo system. The car would start and run but the sequential system wouldn't work at all.

Get the right harness or get a harness that is in better shape than yours.

Also, many times the factory harnesses just need some new connectors and replace the brittle tape around the wiring. A little work can make them look and work great.

I understand that. But I've deleted all of the emissions and solenoids already anyways and am no longer running sequential. In running the twins parallel instead. So I guess in theory I could. But pulling my harness and re doing it, isnt out of the realm of options.

OK, I was confused - typically on the forum people say "non-sequential" for running the twins with all the control mechanisms removed. "Parallel" is more ambiguous. I didn't understand the question properly.

That said, a single turbo type harness would work just fine. At that point you don't need any of the rat's nest solenoids controlled, just need a harness for the fuel injection duties.

Thanks,
Dale
