I have Vauxhall engine and gearbox in my ka (with an aftermarket speedo pickup) so I wont be able to test it using the idle control method unfortunately as I see it I have a few options
1) Use the Vauxhall cruise control unit (as I have the wiring pinouts) and try the aftermarket wheelspeed sensor
2) retro fit ABS on the Ka and to get a VSS for a mondeo cruise control unit
3) Get any cruise control unit and control the motor directly bypassing the need for a VSS
4) Use an aftermarket cruise control unit
5) don't bother with the cruise control!
