Throttle cable. I also used the WRX cable because it is longer. The fitting is different at the firewall but it’s very easy to make it work.
The difference in length.
The brake lines on the RS differ slightly then how they are on the WRX. Just a 90 degree bend is all they need. We used a socket to not put a kink in the line. Do it slowly and don’t use your finger to make the bends and you’ll be fine.
Cover put on.
Heated seat relay. There is a factory clip location on the dash bar that fits the relay perfectly. It’s the pink one.
