On my 2003 mgtf the boot light was not working and the alarm went off when the was boot opened, I stripped the wiring loom down and found several broken wires , following the colours, I`ve repaired all but two , the purple and red wires are broken at the main loom , I gather one goes to the instrument pack and one to the BCU , but which is which ? does it matter?

Maybe this guide might help: https://www.the-t-bar.com/forum/roverlike-s-guides/97856-mg-f-tf-boot-hinge-lid-wiring-loom-inspection-guide

Thanks Roverlike for your reply,unfortunately the wires are in the main loom heading to the front of the car,

Hi and welcome to the forum

As Roverlike says on that linked page, the purple/red wires join in the main loom so it doesn't matter which one joins to which one where you are doing your repairs.
