2018 subaru wrx sti bulkhead wiring diagram

Since its debut in 1992, the Subaru WRX STI has become one of the most iconic cars on the track. With its performance-focused engine, sharp design, and faithful following, the WRX STI is an automotive icon. But one of the biggest challenges for WRX STI owners is making sure the wiring is up to standard.

For 2018, Subaru rolled out a new bulkhead wiring diagram for the WRX STI that is sure to help owners in keeping their cars running smoothly. The diagram highlights all of the wiring locations, which assists in locating any potential fault points. The diagrams also lay out all of the wiring as laid out from the factory. This ensures that any modifications that are made will match up with the factory recommended configuration.

Installing the bulkhead wiring diagram is a quick process that can be completed in a matter of minutes. All you need to do is access the main fuse block beneath the hood and plug in all the wires according to the diagram. If you’re not confident in your ability to wire correctly, a professional installation may be a better option. Either way, having the proper wiring diagram will save time, money and hassle - something that’ll make the WRX STI even more enjoyable!
