Hey H-T!

So I have a 1997 Del Sol S. D16Z6 block with a Y8 head. I have converted it to OBD1 via the OBD2A to OBD1 harness with a virgin P28 ecu. Now, the previous owner cut the wire from the VTEC solenoid and also routed 2 wires from somewhere below it into the cabin next to the ecu that he claims were to wire VTEC. What are these wires for? And how would I go about wiring VTEC when I'm using the conversion harness?

Thank you!

 

Check continuity from the engine bay to the location of the wires.

 

Here is what I'm talking about. The solenoid has the cut wire, and that piece with the light green connector has 2 wires coming out of it that are routed into the cabin and are sitting next to the ECU. What is that for?

 

You can wire it to the adapter harness side or the cabin harness side your choice.

Thank you so much!
