5. The first job is to find the right location for the GSM-5000 control box. The shift cable must not bind or be folded in any way, but can be curved in a gentle arc. The end of the cable needs to terminate at the shift select lever on the side of the transmission. Here, a slit is cut in the carpet, and a hole was drilled for the cable in the floor near the trans tunnel. Next, the electronic harness is attached, and 12V power is connected. The harness will be hidden once the shift detents are programmed and the final position of the button pad is established.
