Added cruise control
I used the Audiovox CCS-100 kit ($90 at summitracing) and the install wasn't too bad. It was a huge pain getting the throttle cable off without removing the carb, but I finally got it off and looped the cruise control servo cable onto it too. After that, it was pretty easy.
I mounted the servo unit just behind the passenger side strut tower since there was room right there behind the coil. I also added an extra vacuum reservoir which they recommended for small engines (got the reservoir and one-way valve for $3 off an older Accord at the junkyard).

I had to modify the slip ring from an 89 prelude to make it work with the steering column of this car. I already had the wheel in there but the slip ring wasn't in place (only the horn was working before). But now I have the wiring in place and the buttons on the wheel work to control the cruise control.
