I'm trying to work out what the deal is with the rear of the fuse box, most pictures of it have a cover on and I'm assuming that a motherboard sits in there normally and is plugged into this plug you can see, I was hoping that it was a wired plug coming out of it so that I could wire my own indicator switch, but I'm thinking it's probably a plug soldered to a board.
If anyone has had it open I'd love to know what's normally in there, as you know I'm a bit lazy and don't want to unplug and unbolt my own to look at it.
EDIT: Never mind I think I've found proof of it, even though it's a lancer ECU I think this is how it would work with ours. This can be deleted if desired.
