My brother is going to start making brackets to hold things that look like they’re all over the place right now. This is just a practice one to hold the plugs you see that are just hanging.


Difference in battery trays. The WRX has a little protector plate on it.


I didn’t post this wiring on the other pages because I wasn’t sure of it myself. I didn’t want to give any wrong info. So to all the guru’s out there watching the thread you probably noticed I “missed” a few wires in my pictures. These wires are as follows:

Off of the SMJ there is a decently sized gauge wire that doesn’t run to the ECU (after almost all of the other ones do). Said wire is the coolant temperature sensor. It goes from the SMJ STRAIGHT to the gauges. I’ve noticed many swapped cars already for sale that said that the coolant gauge doesn’t work. This is the most likely reason why. Sorry, don’t have a picture of this wire.


I said on some of my first pages that I didn’t want to hack job this swap up. I wanted to make wiring look as clean as possible. I also wanted to use every single check connector off the WRX harness. And I have accomplished that. All of the flash connectors and check connectors are hooked up on my car. I copied the way the wires on the fuel assembly side of the WRX harness were and made my RS harness match that. It involved un-pinning two wires and adding a wire that runs from said flash connector to the plug itself.

I decided to get fancy with the camera for the first time this swap as well. Top of the same plug but in the WRX.
