Cruise Control Wiring

[Timp]

Friends, tell me where these go... I'm retrofitting cruise control into my '87 325 and I haven't had time to put this in since I pulled it out of a fellow member's parts car, which was awhile back, and I've forgotten where these wires plug in to. I checked the Bentley manual but I can't read those diagrams to save my life.



1) Green/Brown + Purple/White
2) Blue/Brown
3) Brown (I know this is the ground but there's no where to plug this in. Bentley says 'Beneath instrument panel and above brake pedal' but I cannot find anywhere. I could cut it crimp on another end and just put it elsewhere)
4) Is this where it's supposed to plug into the clutch switch? I'm still waiting on that in the mail - can I use CC without that?

Thank you, and forgive me for my newbness.

1 – ‘Power’ plug. If you file or sand off the little tab on it. Threre's a white distribution box under the driver’s dash. With the tab removed, it will fit into a slot in the distribution box.

2 – This one has something to do with an automatic transmission. Just tie it off if you have a manual.

3 – Ground. Yes – clip it and crimp on a grounding terminal and ground at nearest convenient location.

4 – Clutch. Yes – you’ll need the switch.

Cruise Controls, Connections, Micro Cruise Switch Settings




Most of the time cruise controls are one of the easier accessories to install into a vehicle. Most only take * 45 minutes to install. Some may take longer. Vehicles with manual transmissions may add another 10 minutes to the job on average. There are usually only six electrical connections and only two mechanical connections to make when installing a cruise control into a gasoline (not diesel) powered vehicle with an automatic transmission as well as mounting the control arm and servo.

I prefer to use the Micro Cruise, now manufactured by Rostra Precision Controls, Inc., but there are others to choose from. Each has it's pro's and con's. The information below is most relevant to the installation of the Micro Cruise, but in general will apply to most cruise controls available on the market today.
