Anyone have a good suggestion to what after market cruise control to install?

 

So many on the market. My first concern would be not so intrusive on the dash.

Had one years ago. Switch mounted on the turn signal lever. Turned out to be a real mess. A lot of drilling and really ruined the look of the engine bay. Not to mention the model I had worked off the drive shaft and a lot of drilling into the body. I regret installing mine personally. It’s all been removed during the restoration. A lot of spot welds to fill holes.

Did you find an old JC Whitney catalog? I haven't looked at the modern systems, though your post prompted me to do a quick search.

No real experience, but I haven't been motivated to look into doing it on either of my cars, yet.

I am designing a bolt in Drive by linkage setup, if you had aftermarket ecu, then maybe! 

Rostra seems to have the only commercial consumer cruise control system. Pic below of what I got recently from Amazon.

Just need a speed digital signal. There is a couple of options, you can splice a “thing” (I’ll find a link eventually) into your speedo cable, or if you have a GPS speedo, then do away with the cable all together and use this.

Now the hot tip is as Duffy says, go Drive by Wire and let your aftermarket ECU handle the cruise control duties. And idle control, etc. Its just a big step. There are actuators for triple carbs or throttle bodies too. See what efihardware in Australia  has. Cool stuff  https://www.efihardware.com/products/c598/dbw-components

I have seen a few folks working on nice solutions with 350Z throttle bodies and pedals, what are you doing Duffy?

No ECU. 71 240

 

JC Whitney, the good ole days, some the stuff in there was just so horrible. Good memories.

 

I figured there was a GPS sensor that could be included with some units, I'm just starting to the search.

A friend about 30 years ago did this with his pickup, worked pretty good.

The downside to using GPS for speed is that you need a good solid signal. The more satellites received, the more accurate.

If you are in a wooded area, or an extremely cloudy day, the cruise might not work as well as intended.

I will have a bolt in drive by linkage actuator, that goes behind the firewall.  I have it 95% done. I will also offer a double pull cam for it as well, so two throttle cables.  

 

It will use the 350z pedal.
