I'm trying to install a mirror tap on my 2017 wrx. It looks like the 2017 WRX Mirror is different than previous years - as it doesn't have the little junction box that you can just pull out. Instead it has a cord that actual goes into the mirror. Has anyone ever dealt with this before? Help!
Hate to say it but looks like you're going to have to put a slit in the wire loom and find the positive/negative to tap into if you really want to use a mirror tap. The other method would be to run the power to your fuse box with an "add-a-fuse".
