I put an h22a in a 96 civic coupe we mase a harness using the h22a plugs nd tje 96 civic harness everything runs great no problems at all but i have tried everything i can and can nnot get v-tec to work i even tried both v-tec selenoids with nd without two plugs and got nothing i need help if anybody has any suggestions.

 

There are two plugs that look identical, are you getting a cel? One goes to vtec the other goes to a temp sensor that controls a fan, i had them swapped on mine and the fan still worked but no vtec. Also do you have the correct ecu?
