A great helpful post. Thank you for posting it. I have had my 2005 3.0L Outback for 7 years now and love the car. However, i really regret not getting a model fitted with Cruise Control when i bought it. I have looked online many times trying to find out how to fit it retrospectively and always came up blank. After reading this post i pulled my drivers footwell and steering wheel to pieces and found that the wiring and connections were already in place. I got myself a steering wheel with cruise controls on and fitted it. The computer recognised the controls at start up, but of course i couldn't set it as i only had a 2 pin brake pedal switch. For some reason getting a 4 pin switch proved to be impossible. Tridon have them listed but have discontinued them. Even the local Subaru dealer couldn't help. Multiple wreckers came up empty handed. Eventually i found a way around it using a 12V DC single pole relay: 1. Using the normally closed contacts on the relay tap in to the yellow and green/yellow wires on the 4 pin plug by the brake pedal. This sends the closed signal to the computer that it is looking for to enable you to set the cruise control. 2. Pick up the brown/white wire on the 2 pin brake pedal switch and connect it to the +12V on the relay coil. This is the wire that goes to the brake lights. 3. Connect the 0V on the relay coil to any convenient 0V point. I used the cigarette lighter as it was easy to access. It works perfectly and when the brake is applied the closed signal to the computer is broken and the cruise control is deactivated. I can now drive comfortably without getting an aching right leg and spending more time looking at the speedo than the road in order to avoid giving extra voluntary contributions to Government funds. Thank you again for the original post.
