I am not majorly up to scratch with all the different types of ecu etc, ill say what i am doing then maybe u can help me. Basically i have 2 coupe civics, both lsi models. i have a shell on one with loom already in, and the other is a complete car. i am swapping the engine over and ecu. i have gone to connect the ecu and the plugs are different. i am told that there is some sort of adaptor you can get to change the plus without having to redo all 50 wires. anyone know of anything like this, im told the car getting the engine has an esi plug on it so i would need it converting. can any one help or give me some advice how to swap this over. thanks all
