Ok a somewhat stupid question, but where does the ECU mount? i know it's on the firewall inside the car on the passenger side footwell but how does it actually get mounted? i can't figure it out...so if i could get pictures or a really good decsription, and also a pic of a somewhat clean KA24E engine bay so i can mount the engine harness how its actually supposed to be mounted...THANKS MUCH

Technically, its more to the "fenderwall" than the actual firewall. On the footwell just ahead of the door. There is a 10mm bolt that secures the ecu on the lower side. The connector port on the ecu will be facing inside the cabin.The wiring harness connects, and is bolted down with a 10mm bolt (right in the center of the harness plug) to secure the connector. The harness then wraps over the ecu, up under the heater core and out into the engine bay via the only? oval shaped hole on the passenger side firewall.At that point, it should sorta' just fall into place.I would post up some pictures, but apparently I bought the wrong size batteries for my camera. Hope that helps.
