right, here's what you need for instalation of cruise control on a non cruise control car
a cruise control actuator,
a bcm (body control module) that is cabable of cruise control, you cant put cruise control on a car with out the bcm.
a pedal switch
a second stop switch, (of the stop lamps will do)
basicaly, this circuit goes like this, there are 2 circuits
power and a control circuit
the power circuit runs to the bcm, and there is a latching relay in the bcm that will engage the cca (cruis control actuator) if your bcm isnt cruise control cabable, it just wont work, plain and simple. the cruise control switch has a on/off, and 2 failsafe relay's in it, r/a, and s/c, ra is resume acceleration, and sc is set cruise control, this sends a single to the bcm which will keep the car at the amount of rev's to the engine will work, you need ot also make sure you have got your instruments instalted properly, because there is a failsafe on the cruise on light, if it's not on, the fail safe will stay open, as a result you have a open circuit on fuse 11, which is the main power suply for the cruise control actuator. if you can, please right down the list of stuff you have done for me, detailed that is, i need very detailed descriptions of what cable you have put where, ill tell you exacly what you have done wrong.
thank's
cheers
