Are any other fuses popped right now?

maybe you connected speed sense wire that comes to radio wiring loom to somewhere it doesnt belong

Guess I should check for that eh Ken? All the fuses on that bad bo are from the factory. It seems like I popped a weird fuse in the last E30 I wired a stereo into as well. I'll look.
