  1. First off, my apologies for necroposting this thread, I just wanted to thank Richard Hamilton for his very valuable help on the retrofit and for providing me the hard to find connector for the servo / actuator unit. The provided PDF document was spot on and I got my cruise control working first place (for those wondering, as it's a separate device from the ECU, it didn't need any activation of some sort, flick the stalk switch and get the instrument cluster green cruise control light). A couple of remarks : - the PDF has a small mistake regarding the wiring : Pin C of the cruise control actuator (BK/OR) goes to bridge plug 6/2 (not 5/2). 6/2 indeed bridges the stop light switch (close contact). I don't know why the actuator needs both NO and NC contacts but BS 6/2 bring the NO one. - The real time saver here is to purchase a CC servo plus gas pedal assembly. I got one on ebay for about $160. I asked Richard to confirm before purchasing, but indeed, the regular gas pedal DOES NOT have the middle cam that overrides the manual gas cable. I kept my car pedal installed in place to NOT have to swap it for the new one and saved the disassembly of the main gas cable and cam. I simply scavenged the CC cam from the ebay pedal and installed it in the stock pedal. It was tedious to get there based on the little slack there is (as the tutorial states, 13mm) but I got that done in 2 rounds of 1hr work. - My car is LHD, there are indeed slotted drills in the brake pedal support, it's just freakin' hard to get a pipe wrench in there. It took ages to both see what I was doing and slowly tighten the 3 screws, sometimes 1/20th turn by 1/20, especially the one that is nearest to the dash / up. But I eventually got there :-) - Get some proper fabric tape to make your loom / wire harness. Tesa makes a wonderful one. Never use PVC / electrical tape, that's one of the biggest insult to your car. - My car is manual and doesn't have the kick-down switch. In place, there's a filler part that is sandwiched between the 2 halves of the gas pedal and it's a PITA to keep in place when trying to re assemble it after adding the middle cam. Use a dab of hot glue to attach it to one half, that will easy your re assembly job - finally, my CC unit was NOT provided with all the mounting screws. Researching they are PT10 Ejot screws, self taping for thermo plastic but I couldn't source them easily. In replacement, your can install a blind rivet / stud in the mounting feet of the CC servo, I used Rivkle ones, M5. Drill, a dab of loctite 406 and then use the plier to lock it. As it's not as self locking as the EJOT screws, mount the screws with a dab of blue thread lock (light) just to ensure the servo won't move with the vibration. It should move from the CC operation as it's pulling against the slotted holes and tends to remain in place while servoing. Getting the cruise control was worth the effort. First, just for when I sell the car (if I have to, clearly keeping it for now). It's like A/C, people are now used to it and want all the options in the car. Also, based on the fact that car really wants to go fast, it's hard to drive it on the highway at just 130 Km/h without spending your energy and focus just on the speed. The cruise control is really pleasant to have just for this.
