2003 WRX Wagon rear right electronics replacement.

ShelMan246 · 01-12-2021, 04:16 PM

Hi! I had a fire in my 2003 WRX wagon at the very rear right corner. I am somewhat new to this car, but I bought a running/driving salvage 2003 outback sport wagon for the majority of the cosmetic pieces, and I'll be buying the correct WRX wiring off eBay, but, I don't know what other exact electronics are in that area, there was one crispy ~1.3"x3" small box with what looked like capacitors on top, but burnt beyond recognition. The wiring diagrams also proved to be not very useful... I am wondering if someone had better resources to see what is back there so I can buy the pieces I need.

The black box was probably your fuel pump controller. You'll have to see if the Outback Sport controller can be swapped into a WRX, they might be different.

The black box looks like it could be the rear wiper module but not entirely sure, here are some diagrams thou.
