Starter Relay Wiring
Although overwhelming at first, wiring can be figured out with a little effort. It's a bit similar to figuring out which streets go where and finding which ones to use to get to your favorite places at certain times of the day. There is a learning curve. Fortunately on our older cars, it's not too steep.
Just think of wiring diagrams as a roadmap for electricity. Make sure your freeways, expressways and signaling systems are in good shape and designed to handle the traffic, or you can have vehicles not making it to their destinations or overheating on the roads and catching fire.
