Is this a reasonable option for someone with sequential twins and all the emissions gear?
Is there a pnp harness available anywhere?

 

Depends on what all you want to run. The 1500 will run the engine, sequentials, and purge control but you'll come up short on outputs to also run the OMP. If you need to run everything, you'll need the 2500.

Don't think Haltech has a sequential patch loom yet. We can build them though for either ECU. We can also build full replacement harnesses.
