cruise control problem

[randomdave325]

hi all. it's not often i ask for technical help but this time i'm really confused
i've just fitted cruise control to my iS racebus and it's all gone well up until the final job of plugging in the 2 pin plug to the connector block behind the glovebox. the space is there but there are no pins
the wire colours on the plug are red/green and purple/white.
i assume they are just brake circuit and power but does anyone know which does what or where else i can tap into?
has anyone come up with this before?
i've never had any problems on the ones i've fitted before i just assumed they were all the same.

typical isn't it when it was a quick 20 min job before i go home.
my car was originally a 1990 318i auto touring.

i've sussed it!
green/red is brake signal
purple/white is 12v ignition live.
sorted!
Typically my car is the only one i've found without the pins there but hopefully this will be of some use to someone somewhere

Very strange the pins are missing! the purple/white should connect to purple/green in the car, which is the live feed to the brake light switch.
I.e. The two wires you need are the two that go to the brake light switch.

i have got the same issue i dont have those two pics in the accessory block

so should i just connect these to the brake light switch wires or can i find these somewere near the glove box?

They are in the loom that goes across the glovebox. If you can find them, you can splice into them, but I think it would still be easier to run a couple of wires over to the brake switch.

Brian i also have a blue/brown single wire i have a auto gearbox where shall i connect this and to which colour wire?

cheers

It connects to a green/black that goes from the starter inhibitor switch on your gearbox selector to the starter inhibitor relay in the glovebox area.

hi brian im fitting my cruise control in

i got the green plug that goes behind the speedo which pin do i need to plug the speed detection wire into so the cruise can work

i have connected the double plug which has purple/white and green/red to the wires on the brake switch

and im going to connect the blue/brown wire to the green/black as its a auto aswel

just to check are these correct thanks for the help

[Brianmoooore]

Pin 1 is the correct one, but, IIRC, most of the pins are connected together.
