Hi 

I'm new to group so hope you all bear with me 

I'm going to fit running lights to my x3 using a relay that I have had before and found very good . The problem I have is that the relay connects straight to be battery, that's ok for the positive as supply can be found under bonnet but I need a negative too , that's where I'm stuck😥

Hi Richard...welcome to the Forum!

I'm not sure but if you run a multimeter around the car, I'm sure there must be something local to where you want to locate the lamps.

Let us know how you get on with it

On the X5 all negative/Earth connections are Brown. I would run a single fused live to each running light and pick up a local earth connection to save running tow cables. When i did my angel eyes as running lights I used the headlamp earth wire to tap into.

Hope that helps

      BMW 318i boot locked can’t get into

      Update: I checked my battery and it charged in 5 minutes, so I don't have to find another alternator. All seems to be OK except for the plastic "L"s with a short rubber hose that bypass the HV/AC solenoid. Those get clogged after @ 150,000-190,000 miles (if distilled water wasn't used) and cause air pockets that try to burst radiators. I have a few more brass "L"s, so now I can throw the plastic ones away. I have to be careful I don't fog the windows though, without heat or cool.

      105C thermostat replacement

      You are absolutely right. The strange thing is that when I put the chassis number on the realoem it shows that the temp sensor is not applicable on my vehicle. I will physically check for a sensor. In the meantime, do you think that the removal of the MAP activated thermostat will effect the temp gauge on the dial instrument item 6? I am tempted to add a dummy resistor , 11.5ohms - 13watts , to simulate the MAP thermostat. Your thoughts?

      SLIPPING CLUTCH

      Morning Andrew I normally disconnect the Neg lead only, some folks disconnect both a few even say disconnect both and touch them together. Goes without saying both sensor plugs need to be checked and a squirt of contact cleaner applied never hurts 😅 Dave

      SLIPPING CLUTCH

      Hi Dave, I fitted one of the sensors on the rear but it has made no effect as the light is still there, I will fit the other sensor tomorrow and see how it goes then. You mention the disconnect the battery, is there any pattern to this ? is it both leads or just the negative lead? cheers Paneuro.
