Need your help I have a P2M ecu but my engine is d15z7 wc is 3stage vtec. My question is how to engage the dual vtec since my ecu is good for single vtec only? Thanks in advance

Twist both vtec activtion wires together then add in the lead that goes to the ecu.

Then when vtec activates in the ecu it will open both solenoid at once.
