Well this is happening...ABS & Brake Light + Speedo
 
So I was driving home tonight, and all of a sudden the ABS and parking brake lights came on in the dash, and the truck shuttered, and shut off!

...I rolled to the light, and I got it started right back up. Well, the ABS & Brake lights stayed on and the speedo wasn't working anymore. Great.

So after reading many forum posts, it seems similar to what other people have experienced - BUT, it seems mine is the only case where fuse 30 (the spare but not really a spare) KEEPS BLOWING! When I noticed it was blown, I replaced it and it didn't fix the problem, so I checked it: blown again. I did it a third time just to make sure.

I then disconnected the rear speed sensor on top of the pumpkin in case it was broken and shorted, and replaced the fuse....blown again.

If anyone has any suggestions, I'm open to ideas! Thank you!

Update: I disconnected the ABS module and tried again....blown fuse. I guess that means at least it's not a blown ABS module!

Unplugged both front wheel speed sensors and tried again....blown fuse.

I have no idea what else could get it's power through this fuse.

Anyone?

I managed to trace the supply wire from the fuse....all the friggen way under the vehicle, and then across.....to this....what the heck is this??? It's definitely the culprit. Everything else is plugged in, I turn the key, ABS and Brake lights go out.
