I woul like to know where the wire harness goes after in goes through the firewall. Does it go striaght to the ECU or does it also go to the instrument panel on the dash board and guage cluster. My friend has a 91 4dr civic and we have a 94 LS lying around and we would like to know if it is as hard as people say.

If you have done it before or know someone who had done it before please tell me everything I will need.

Thanks.

 

You'll need mounts, axles, a wiring conversion harness (if you are going to use an OBD1 ecu), a cable tranny, and of course tools and a manual of some sort. As for the harness, the wiring splits, some goes to the ecu, some to the gauge cluster and some to the instrument panels.

I suggest that you use this: https://honda-tech.com/zerosearch
