Installing Cruise Control, thoughts Options

[97celiman]

alright so the 3 options i dont have for my car are premium sound, CC, and abs
i dont know why, i know it started life as a company car (partly why i bought it maintenance was spot-on)
my question is this, besides getting a knew steering wheel assembly (or just the CC wheel control part) what else is involved in installing cc? is this even fathomable? no i would not be doing this-way over my head, just getting the parts and giving to some sort of shop (or someone on here tweak *cough*)
does it involve messing with ecu/harness i know you need the computer in the engine bay, do you need other fuses and all that?

any thoughts would be appreciated
thanks

If you are looking to retrofit toyota cruise control from another celica, there are two different cruise control setups apparently.

The most common is with the cruise control actuator located adjacent to the battery and the radiator. On some models (eg 3sge), there is an air reservoir at that location:

... so you'll need to remove it and blank off the appropriate outlet on the rubber duct between the air filter and the throttle body.

The alternative location is near the abs actuator (between the water bottle and the strut tower) on the other side of the engine bay.

Unfortunately, if your car didn't come with cruise control as standard then the wires won't be present - you'll have to run them around the car yourself. It is pretty straightforward. For a manual car, from memory:

* fit the clutch switch, one wire to a junction box and the other to the cruise control ecu
* a bunch of wires from cruise control to various junction box locations (11) and ground (1)
* two wires to the cruise control instrument panel lever
* fit cruise tell-tale light in instrument panel, run wire between instrument panel and cruise control ecu
* replace 2-pin footbrake switch with 4-pin version
* seven wires from the cruise control ecu to the actuator in the engine bay, one via two sides of the foot brake switch

* plus, fitting the accelerator pedal lifter and the actuator cable between the lifter and the actuator
