O.K so I know this is probably already been posted somewhere but I can't find it so if you could help me or just give me a link it would be much appreciated. I have a 93 cx with a D15B7 swaped to D16Z6 with a P28 I need to know which pinouts on the computer are for vtec and if I have to add connectors or are wires in harness already, just need to find under the hood and splice in or are new ones needed right from the ecu plugs. Thanks. Also where is the easiest place to get my tach signal from?
