Username Post: Adding cruise control        (Topic#344236)

I have a 1982 Z28 with the stock 305 4bbl version of this engine. The car only has 2,998 miles, so I want to preserve the originality as much as possible.

I would like to add "factory" cruise control. It looks like I can get most of the components off of Ebay and some parts suppliers.

My question - for a car NOT originally equipped with cruise control, is this a feasible thing to add? Any pitfalls to look out for?

thanks.

If you haven't already, it would be best to get a factory service manual for your '82 and study both the mechanical, vacuum and electrical portions of the manual(s); it should give you a general idea of what you're up against.

IIRC, there's 1982 assembly manual out there which should show how the factory routed the cables, vacuum lines, etc. The drawings within may also provide some GM part numbers. Although, they may have been superseded and NLA by now.

I think GM still used a CC transducer with speedometer cables running into and out of it to control/measure road speed. I would try to avoid ebay parts, especially if they're used. Installing used parts of unknown condition and then trying to troubleshoot function issues will just lead to frustration.

You mention that your car is a low mile example of a Third Gen. If you're really concerned about "originality", it's best not to deviate from your car's factory configuration.

Years ago (maybe 20), I added cruise control to a '84 Camaro with a V6 and 5 Speed. It should be exactly the same as that conversion, and was relatively easy. Having a shop manual would help a lot in the installation, but I didn't have one. Since I was able to remove the system from the donor vehicle, I knew where everything needed to connect. The car does use a CC Transducer under the hood mounted just left of the radiator, which means that your speedo cable goes from the transmission to the CC Transducer, and then from the CC Transducer to the speedometer. It involves mounting the CC transducer to the inner fender, mounting the cruise control switch in place of your turn signal lever, and routing the speedo cables, vacuum lines, and wiring harness to the transmission, speedo, control switch and brake and clutch pedal switches if needed. So, what I believe you'll need for parts is:

1) CC Transducer
2) Speedo cables to and from the CC Transducer (although I think the one you have can be used from the CC transducer to the speedo, but I'm not sure)
3) Throttle cable from CC Transducer to carb.
4) Vacuum hoses from engine to vacuum reservoir to CC Transducer
5) Cruise Control wiring harness with vacuum hose through firewall (note: manual and automatic wiring harnesses are different)
6) Vacuum Switch mounted to brake pedal
7) Cruise disengage switch for brake pedal
8) Vacuum Switch and Cruise Disengage switch for clutch pedal (for manual transmission only)
9) Cruise switch to replace turn signal.
10) Vacuum reservoir
