The big rubber plug that is on the cable goes thru the firewall. You have to remove (cut with a razor blade) or wiggle like crazy, the rubber grommet off of the cable. You won't use it. You will need a socket like 8,9, 0r 10mm to get the cable off the firewall, and to bolt the adjuster on the firewall. You will need a light for under dash. You will need some wrenches and sockets to unhook the cable down below. The top just hooks under the dash bit can be a rip to get hooked up while standing on your head. Also the cable is bolted to the front frame rail with a small bolt. Don't forget jack, stands, and PARKING BRAKE or wheel chocks.
