MPI ECU electrical before IM goes back on?

[staying_tuned]

I need to wait a few days before I can walnut blast the valves in one go so I was thinking of handling the ECU harness wiring in the meantime, the idea being to handle the ECU wiring and then connect the injectors (already on new PR rail) after the manifold goes back on just so the overall progress isn’t halted entirely while I wait to blast.

Is this a stupid idea?

It can be wired into the ecu before installing the rest. Just take the time to route it along the main harness run back to the rail.
