Hello, I need to locate an [ under bonnet ]ignition controlled positive feed suitable to supply recently fitted all day running lights using an auto relay designed to switch the lights off when the side lights are switched on. I can not locate a wiring diagram from anywhere. All wiring installed, just need an ignition fed positive supply connection preferably close to the fuse boses. The vehicle is a 2008 Grand Cherokee Overland Many thanks Dick XXXXX
Thank you for checking but I still need assistance. Ideally from someone who is familiar with Jeep electrics. I'm sure the answer is very simple but I don't want to cause a major problem with my car should I get it wrong.
Due to a hospital procedure I will not be contactable from 14th August until 16th August inclusive.
Thank you for your response but one of the reasons I was looking for an underbonnet connection is so I could tap into an identifiable cable that has sufficient capacity to take the extra loading. I had thought about your suggestion but knowing how the electric system on this Jeep will shut down when it is not happy with a particular configuration then I was not going to take the chance by going in blind. No disrespect but I went to this site because it claimed to have a Jeep expert on hand to assist. What I am hoping to discover is the colour of the cable that will do the job. The power supply line is already fitted with a 7.5 amp fuse feeding into a12v relay switch.
A friend of mine did something very similar. All worked well for several months and then the problems started; various items failed to operate after the initial switch on process. It could be the windows one day, the radio and sat nav the next or upon start-up the the audio system would fail. He removed the wire from the ignition,had the on- board processor re-programmed and all was fine. Re-connected the wire several weeks later and his problems started all over again.
So you can see why I want to get this right. Jeep dealerships are few and far between in Mid Wales so I don't want to take any chances.
