Here's a few pictures.
The actuation unit (a Rostra 250-1223, which I wrapped in black rubber) sits by the coolant overflow tank. The wiring is routed along the firewall, behind the engine and into the cabin through the grommet that lets in the tach cable.
The actuation cable comes around to the top of the intake manifold, by the CSS. Its end is attached to one of the levers on the throttle rod. The control switch sits just in front of the console, behind the shift lever. No holes drilled.
