I used a factory headlight switch......you can see it in one of my interior pictures. Its in the factory manual choke location. Its kinda lame if you're into chrome and billet, but my requirements were to keep it factory appearing. I wired it so that pulling the switch out, like the headlights are on, enables the cruise. To engage the cruise you rotate the dimmer part of the switch. The dbw setup on the genIII tac module has everything you need. I didn't bother with an accel switch, it wasn't that important to me. The lame part is that the tac module needs to see a high to low transition for the engage input, so you you have to rotate the dimmer switch towards the on position then back to the off position. The dimmer is just a potentiometer, so you only have to rotate enough to generate the correct voltage for the input and then back. It works well and is safe. You have to have the switch pulled out to use it and the tac module has an input for the brake switch. I did have to use a relay to get a normally closed contact. I'd like to put a small torsional spring on the dimmer part of the switch so that it will spring back and feel a little better.
