If i buy one for my vtec controller. Will i be able to use it if i change out my ecu to an obd 1? So since the vtec controller harness plugs into the stock harness, then back into your ecu, if i get an Obd 1 ecu, would it work if i plugged my vc harness into stock harness, then into the ob2>obd1 harness, then to the ecu?
