i put a b16 into my 96 civic ex and changed the engine wiring and ecu but kept the body wiring. the engine is running and no check engine light but my horn, mirrors, hazards, and door loks are not working. should i have changed all the wiring or is it just crossing somewhere? also where can i get a wiring diagram from a 96 civic ex and from a 99 civic si on the internet? does anyone know?
