My ute doesn't have, and has never had AC so can't help with that much. It is a 89 model so has EST, and did have plenty of emmisons rubbish that I've removed Overview These are either for AC (never fitted) or a PTC heater that was definitely on early 3.3L and I've heard some late model 4.1 had them as emmision control? It was basically a heated element for while the car was cold. Either way mine doesn't have it there. Fuel cut off solenoid. Closes off the fuel circuit when car is off to prevent anti-run on. Will run with it disconnected, won't idle, and runs poorly. Red wire from carb is the throttle position sensor/switch. Pretty sure it only knows if throttle is on or off. Yellow wire is 7V supply to auto choke from carb. Only hooked up for this photo I have the choke wound way way way off and the yellow wire off normally. This shows dizzy plug, on the dizzy itself, temp sensor wire (red one going to front of motor) and another emmisions connector, something to do with charcoal cannister I think. Another connector here for something. No idea what. That red wire connected to the fuel cut off solenoid... I've just noticed that mine has been connected to the coil and the blade that it would clip onto the solenoid is gone burger. I've been chasing a rough idle, shit house start and slight run on and wonder if that's the issue or atleast a factor? Curious to understand how/why the wire can be connected to the coil and the engine will crank and fire but if i take it off it wont fire? Share this post Link to post Share on other sites
