Electrical wiring in boot shall I repair?

ok,
So in a past life my mgf had the boot hinge wiring issue. As shown in the photo wiring has been cut which means no boot light or alarm. A feed from the rear brakes has been put in to supply the high level light. My question is shall I repair the cabling or let sleeping dogs lie knowing that the wiring is not correct?

Well personally I couldn't live with that but it depends on how confident you are in making good the repair . As with most things like this access is the problem . Just connecting the broken wires with chocolate block type screw connectors is not good so , the repair for me would involve installing new wire . The repair in my view needs to be taken away from where the loom flexes and eventually breaks . I know I'm probably making this sound more complicated than it is but with wiring I have found its best to make the repair as good as it was when new or it will let you down again .

I had this problem, I stripped the loom covering back, soldered in new sections of wire between the broken ends and slid heat shrink over the joins and re-wrapped. It's a bit fiddly but not too difficult. When reaffixing the loom I didn't use the fixing on the hinge as I think this is the problem as it causes a sharp bend, and let the loom take its own shape.

OMG, that is bad, at the very least one should insulate the ends of the broken wires.

I have been working on a curly "kettle" patch repair cable, I have one on my car but haven't had it on long enough to confirm it works.

I believe that MG/Rover issued a TSB for this boot wiring that involved removing one of the cable ties that hold the loom to the boot hinge to enable the loom a bit more freedom . When I bought my 05 plate TF , the loom had one of the ties on the hinge cut and earlier this year I checked the loom and the wiring is still ok . While I was working for London Taxis , this sort of loom flexing and the fracturing of the wires inside was quite common on items like the drivers and passenger rear door , due no doubt to the constant opening and closing of those doors . Just making a repair at the point of the break was not a good fix as the repair was generally thicker and less flexible than the original and the added thickness left the wiring fighting for space within the loom / conduit . Taking the repair away from the area where the loom / conduit had to bend is the way to go and, also spraying silicone into the conduit helped the wiring slide as the door shut .

Fix everytime - exposed wires mean short circuits are possible - worst case scenario car on fire! its not that far away from the fuel lines!

Thanks for the advice.
So I repaired using the guides published. As suggested not too difficult, just very fiddly.

Top tips from me.
Use black cable for the earths, it saves a bit of time when checking and Feels more correct.Not sure if it makes a difference but tried to work out the correct path way for the black wires, not just join black to black.
Don’t wrap your wires until you have given it a good run and got heat in the engine bay. Allows for easier checking and weak joint checking.
Use a powerful enough soldering iron and a strong flux especially for the existing wiring ( I used a plumbers flux
Play some floyd and chill.

Oh yeah, that's my kind of car maintenance :tada:

Every circuit from the boot loom has its own earth but they all go to the same terminal on the body so it doesn't really matter.
