Is this the throttle cable?
http://cgi.ebay.com/ebaymotors/Cable-Actuator-Focus-Zetec-2-0_W0QQcmdZViewItemQQcategoryZ33598QQitemZ8004090997QQrdZ1It's soo short, it almost looks like the ATX shifter cable.
I bought a Focus Central TB a whie ago and never got around to putting it on because the cables didn't work.
TIA,
