the two green wires are the vtec one is the sensor and the other is the cylinode i have the gsr harness to the dx harness the dx has no vtec so the wires were run seperatly instead of in the harness the problem is i dont know where the two wires go i bought the car with the engine swap already done so i dont know how the origanal owner wired it into the computer but then again you could be right about not getting the same computer back do you know who i can give the serial number to to seeif it is an 98 gsr computer
