How to read Automotive Wiring Diagrams
There are a lot of things to consider when looking at automotive wiring diagrams. I will start with the absolute basics. The top of the wiring diagram usually indicates where the “power” is coming from for the specific component. For example, if you are looking at a wiring diagram for a fuel pump, the power source is going to be at the top of the page. Either a relay or a fuse from where the fuel pump gets its power. If you are looking at a power distribution wiring diagram, the power source will be located at the top of the page. Main fuses or even battery supply.
The bottom of the page is the Ground for the specific component. Sometimes components will share a Ground and sometimes they will not. Assuming all of the grounds are good, they will all eventually lead back to the same place.. the battery.
