i have a 91' civic si with a swapped b16 and i have a short some where... theres a red & black, and a brown & black wire that's hooked up to the ecu... does any one know where they run... because those two wires always blows me ecu fuse.

 

I've had that before in another car. What I did was follow the wires from the ECU fuse and look for a pinch. I had to take a few things apart but I found it.
