Uprated headlight loom / temp sender? Help

[Rich the Chef 10]

Hi. Well the 'rado failed it's mot for not having dip beam...there is an awful homemade setup there at the moment. Plastic outdoor lighting junction boxes and yellow tape everywhere...

So I'm after some fitting instructions for an aftermarket headlamp loom... It came with the car and is a 3 relay setup.

It has two genuine connectors with a wire coming off each. Which I presume are for fogs?

There is the battery lead and three relays and a cluster of spade clip ends...

I'll try and post a photo. But if it's similar to anything I can use as a guide I'd like to get it fitted.

Also which sender do I replace on a VR6 to get the temp gauge working correctly... It's currently showing mid 60c at run temp. Fans working fine.

Thanks
