Ok here is a tip for you, If your doing your Minis electrics then I recommend you also have one of these in your tool box
A Sealey Auto Probe.
PPI Auto Probe
They connect to the + and - terminal of the cars battery and you can probe wires and test for bad earths and confirm live feeds with one.
If you have a indicator which is not working then you simply slip the bulb out probe the centre pin and the led lights up to tell you its live so you pop your bulb back in and do a earth test by touching the probe on the earth of the indicator lamp and pressing the negative on the switch, if the bulb flashes you have a earth problem.
Your also able to make the probe tip 12v so you can provide a temporary feed and power up a circuit, this is also done on the rocker switch.
Makes life so much easier on fault finding and far faster that making up wires, you can get the basic one for £14 inc p/p and the PP2 for £20 with a built in work light. You can spend £100+ which is my daily all in one with a lcd screen and built in voltmeter and scope, but thats not required for the home user and I started out with the PP1 and its still running today.
Something I'd recommend.
Here is a short video of it in action
