okay here goes...

use your stock dx/cx engine harness. You will need to lengthen and move around most of the wires on the intake manifold to fit the y8 manifold.

IACV: On the y7 harness the iacv plug is three wires; blu/blk, yel/blk, and orange. The y8 iacv has two wires a blu blk and a yel/blk. Splice the matching wires together on the y8 two wire plug and just cut the orange wire a little short and tape it up so it doesn't contact anything. At the ecu you will need to move the blu/blk wire from A12 to A14. At pinout A13 the cut the orange wire away and tape it up.

Vtec Solenoid: Run the one wire from the vtec solenoid to A8 at the ecu.

Vtec oil pressure switch: There are two wires. Run the blk wire to a good ground. I use the thermostat gound. Run the blu wire to C15 at the ecu.

There you go. Sorry I forgot to return your pm. Tell Charles to call me if he still has not figured out his car.
