[TR] TR 250 (TR4) Cruise control

[DAVID MASSEY]

 I have the Audiovox on my TR6 (which is a close enough analog) without the vacuum canister.  Works just fine.  I mounted a bracket for the cable on the shelf in the firewall and used the beaded chain attached to the long linkage that runs behind the carbs.  I can send pictures if you like.

Hi,
We are planning some long excursions this year in the TR 250, so I would 
like to install a cruise control in the TR 250.

There have been two basic options mentioned in various posts.
1) The Rostra unit which is more expensive and seems to require have 
more installation requirements (for example a sensor on the drive shaft 
to register speed.)

2) The recreation of the Audiovox cruise control, which requires a 
vacuum canister. Quite a bit cheaper than the Rostra.

I have seen articles for installing both, but on carbs with a cable 
linkage but none with the throttle linkage like the early TRs.

Has anyone installed on or the other on a TR250, TR4, etc that has the 
rods, levers, bell crank arrangement? If so, how did you make the 
connection?

Thanks,
Roger Elliott
