I would like to disagree with thist approach. As they are both obd1, your stock harness will work and all the plugs are the same. If you have an si (already vtec), then every wire should already be present. All you will need to do is lengthen the wires. You can solder or be cheap and use nuts. Either way, all plugs should line right up. That's the point of having a wiring standard to begin with. This will trim MANY hours off your time, as replacing a harness is the worst excercise (imho) anyone can go through.
