a form follows function wire tuck will take awhile on an EG. Since you, I believe, are starting with an EK it will be alot easier.... In fact Honda aready gave you a wire tuck. On an EG i would start with an EK engine harness(converted to obd1 ), and reroute everything while the engine is out. Engine harness pass side plug would be laced in with the rest of the wires to the ecu. Then, basically remove(one by one) all wires from pass shock tower all the way to the ECU(you will be going into the main harness, make sure you know what you are doing). Then I would pull the drivers side wires throught the firewall until they all sit under the dash. Do not delete these wires, they feed power/& gauges. You will extend/mate these wires to the BIG plug on the EK harness...somewhere under the dash near the ecu. In the end all the wires to the engine will go through the same hole on the pass firewall. To disconnect, all you would have to do is unplug the ecu/BIG plug and push the wires through(almost like the EK). All that just for a tuck......
