I recently installed a reversing buzzer by just hooking it up to the left reversing/ backup light. Works fine for work purposes but sometimes it would be useful to switch it off temporarily...eg leaving a motel carpark early hours. So I thought I would fit a simple switch. Tried to find the circuit and fuse which goes to this by description but no-luck. Eventually by a process of elimination found it was the "ECU-IG & GAUGE".10amp. Haven't changed anything yet as obviously this goes to the ECU, which I assume is Electronic Control Unit? so may be the computer or emission control. So I have to come up with PlanB and wire the switch more locally to the reversing lights themselves. However after replacing fuses the "engine " indicator stayed on the dash. Didn't appear to affect any functions whilst driving but the Manual says "Take vehicle to Toyota Dealer". However after a couple of stops and restarts it stayed off. Should I need to do anythoing else (apart from not removing fuses indescriminately in the future) ??? The model is a 2009 Hilux 4x2 SR 4L Petrol Thanks in advance, Rod
