ok just got my vtec motor in ran the wires for the vtec solenoid, and vtec oil pressure to the p28 ecu- no trouble codes now i think vtec works but i need to know if i need to run a wire from the ground on the vtec solenoid to the chassis too?

 

All you need to do is ground it. Chasis, wiring harness, doesnt really matter.

 

thanx man, thats what i needed, cant wait to see what this does already outran my old crx with a $3000 built engine. cant wait to tell the guy that that was without vtec.lol
