I initially faced the problem of a location near the coil until I removed the old vacuum cruise control servo. Note: after about 3000mi of driving the only complaint I have is the steering column-mounted control shuts off when there's a jolt hard enough to the camper. It happened maybe 6-7 x's in that amount of mileage. Not sure if the reverse kind of unit might be better (normally open vs. normally closed). I have to go back to see what my unit is.

Here's the "Blind" side of the vacuum servo I removed. No information on the web about Specific Cruise Systems other than company mentions. And here's the Rostra unit attached in it's place. Just took 'er out for a shakedown and I might have a little too much slack. But it works well enough to use instead of switching feet or other non-cruise solutions. While there is significant research and set up needed, I think the Rostra unit is well worth the time, cash and effort. Got mine through Amazon

Thanks, Payaso!! I had a mechanic eyeball the picture and his conclusion was much the same. I removed the unit, plugging the vacuum tube with a high tech device known as a golf tee. Everything seems good. I am about to mount the Rostra cable to the same point used by the old vacuum driven cable. I'll update with results. Thanks again!

I'm in the process of installing a Rostra unit in my 1991 Toyota V6. Can anyone confirm the vacuum servo is from an old aftermarket unit (see pic). It looks like the perfect attach point and I would like to get rid of the old vacuum servo if indeed it is what this is.
