Does anyone have a couple of pictures of the Clutch and Brake Pedal of where the Switches and Sensors are supposed to be positioned on the Clutch and Brake Pedal? Also on the 1990 300ZX Z32 model's on the 2+2's on the Driver's inner Wheel Well there's a metal square housings that has wires coming out and through the firewall. What is located in the metal Box? My Green Light illuminates but my Cruise Control doesn't work. There's a system check that you and start the car holding the set button down but I can't get it to work at all. Any ideas or inputs would be grateful.
Thank You so much!

Chances are the "Lifesaver" Green Plastic Pad that the actual Clutch actuator Cruise Control switch plunger pushes up against is cracked and broken / missing. This is a common failure, but luckily they are less than $7.oo and not too hard to replace. Ask your NIssan dealer about these....

You can get these on CZP, they are called pedal stoppers
