The other day my abs and park brake light came on. I checked the fuse and it was blown. So i repalced it and it blew as soon as I started the car. I checked the wiring at both front wheels and at the diff. I cannot see there is a problem. Has anyone esle run into this. I just installed a line lock the week b4 and a magnaflow catback. The brakes work fine but i have no abs. Is there a code that will be triped, b/c I cannot get my engine light to off either.

Thanks
