Delete Cruise Control on an SC

[kalawao]

Hey Pelicans,

I am in the process of removing my Cruise Control and have read all threads here but I am still uncertain with one thing:

My idea of the servo in the engine compartment was, that the throttle hose that Comes of the servo is the actual throttle line (which is somehow connected to my pedal and my right foot ;-))

But other than those vacuum hoses there is nothing but a power cable.

Is it correct to just remove it and the actual throttle cable is somewhere else connected to the engine?!

I want to delete all parts no longer needed therefore I want to remove the servo.

Help is appreciated.

Best, Martin

The servo, round drum looking thing in eng comp., has a cable that connects to the throttle bracket on the throttle body..not the pedal assembly. It uses electrical signal from stalk and vaccume from engine to hold the cable that attaches to throttle body in position.
The cable to connect to the throttle body should come out the servo end that faces the rear bumper of the car. Your cable may not be there as previous owner may have removed it as the end that attaches to the engine is known for breaking.

Also, it's very easy to remove the Cruise control lever at the steering wheel. Just unbolt steering wheel and unscrew the cruise control assembly from the stalk. Next follow the wires under the dash and unplug at the connection. If I remember correctly I think you need to separate the plastic cover around the Steering wheel stalk. You can then pull the Cruise control lever and wiring out as one unit. No cutting required.

Thank you both for your answers ..

The lever at the steering wheel was easy and so was the cable ..

The weird thing (must be my mind ;-)) was, that I always thought that the cable that comes out of the rear facing of the servo is actually the throttle that is connected to the pedal in some way (and just goes through the servo and will be held there if I use the CC).

So to sum things up: I just remove the cable and the servo and all parts and everything will be great, right!? ;-) no need to use some other cable and connect it to the (old) connection on the top of the engine ..

Isnt there also a control box in the frunk near the master cylinder?

There is a control box in the front and a switch in the tunnel (for the clutch)...and associated wiring between everything.

Just need a quick confirmation.

I removed the cc servo unit from the engine compartment and plugged the two vac lines (one small and one large) with rubber plugs--are these plugs sufficient to plug those lines?

I just did this today also .

The big one is a vent. You can just pull it out.

Anyone have a picture of the CC servo?

You can see mine in the top left.

I’m fairly certain the throttle linkage is solid rods with lots of pivots and joints going from the pedal to the throttle body.

It is on my 84 3.2
Cruise is the cable…easy peasy.

Does anyone make replacement cruise control throttle cables that aren't silly money? I mean it's a bowden with a funny clamp at each end, why is it so pricey? Maybe when it finally breaks most owners just say "well it was good while it lasted" and call it a day?

Anybody do repairs on them? If I remember it's just the plastic clamp that holds it in place at the throttle body that tends to give up.

Honestly I don't understand what someone would remove the cruise control on a street car. On my 85 911, I use it on every road trip and I love it.

You will have to source a cable on Ebay and it will be used, or fight with the lousy scammers on the WTB site on Pelican. Maybe one of the folks in this thread will sell you their cable.

The tricky part is the plastic clips on the end of the the cable at the end on the throttle bracket. The clips are almost always broken. Just use two zip ties in a X pattern to hold it securely in place.

If one is building a track oriented car, yea, strip out all unnecessary parts. For a street car, cruise control is a wonderful thing if you actually drive your car like it is intended.

Don't get me wrong I love it and use it all of the time in my other cars, just that it never functioned in my 911 since I bought it in 2013. Whether a servo or computer failure I don't know, but on top of everything that clip was broken so I never looked into troubleshooting. I guess I should have gotten into it earlier but it was always at the bottom of the list, you know?

My wife is having a baby real soon, though, so troubleshooting cruise control is going to have to wait a little while longer!
