1993 Civic CX LS B18B1 - not sure of OBD series (i guess it's a 1) LS Manual trans I believe it has the factory wiring harness. I know people say it just plugs in, but I acquired a messy setup and I need to verify which plug and vacuum connection goes where. The ecu is said to be chipped for 7psi. I really do appreciate help..... Wiring from drivers side. The plugs are are pulled taught so you can tell which ones longer than the other. I don't know where the tube is for this. I might need to make one. But I need to know it's route. This is one connector that matchs a plug from the 1st picture. Another connector that I believe uses a plug in the 1st picture. AND sloppy wiring to the speed sensor that I am not sure if it is correct. Another connector using a plug from the 1st picture. Vacuum hose to where? ECU splicing that I haven't been able to verify. Some sort of splice that is confusing.
