I see the ecu diagrams, but do not know what wire goes where on the solenoid itself. Any insight would be great

 

Boost solenoids dont have a + or - side. They're interchangable. So don't worry about which wire goes where.

With that said, would I be correct to say, one side goes to the ecu, one side goes to 12v constant? Assuming the ecu output is a ground output.

Edit: I forgot to mention, the factory bcs wiring is not available. The original builder didnt want to use an ebcs so the harness was taped up. To take advantage of a Grimmspeed bcs, Ill need to run the wiring.

 

I will need to check the diagrams but I would assume one goes to the MPI relay and the other to the ECU.

You maybe correct. I see one end of the bcs going to fuse #2, main engine fuse. And the other to pin 11. I found this good diagram for a Hondata solenoid, so Im confident any switched 12v source on one end, pin 11 on the other.

Ima give it a try this weekend. Otherwise, have a mbc ready to be installed too.



Its funny Hondas use the same pin 11 wire..
