I bought an imported Altezza Gita with 2JZ. I would like to fit cruise control to it because it doesn't have one.
With couple of hours googling, I have figured out that I'll need at least new spiral cable capable for 6 wires (84306-60050) and of course the cruise control switch (don't have correct part number yet). Also, two new wires from ECU are required to spiral cable connector, found diagrams and ECU pins easily for this (if ECUs are identical between IS and Altezza). Hole for switch needs to be cut through steering wheel but I believe there are mounting points already.
Are there differences on the throttle body between IS300 and Altezza? Do I need something new in engine bay?
Trying to find out all required parts, before spending couple hundred to find out I need more parts.
