I believe you also know how to tape wiring. If not then youtube it,
Its done with non sticky plastic tape (very readily sold in Karachi almost anywhere) always wrap from outwards to inwards and start with the tape on the wiring first a few twists then feed it through the slit in the loom and neatly wrap it with a 50% overlap with some stretch.
When you come to a joint or a take off, you need to tie a knot in the tape so it remains put. Then you can start the wrap once again till you get to the end taking care to wrap in any plastic holding buckles in the wrap. Its a long process but best done on a table with a chair pulled up.
Tie a double knot at the end of the loom, or use a wrap of silicone fusing tape to finish the wrap.
You can use green and white electric tape to “mark” the hanging brackets etc like the factory did.
Dont omit the fusible links from the positive terminal of the battery, its the square “grip” with a slightly heavy wire in it, it actually is the fuse of the main positive to the alternator, if you are daisy chaining from the starter then install the link on the starter lug (early SA310, swift, khyber had it on the starter and later one had on battery like mehran)
Btw lahore cables in plaza market sell really good quality wire like used in the factory, but are pricier than the scrap market, problem with scrapyard wire is that you never know if the conductors are corroded internally.
Long ago a customer of mine made an alternator positive from such wire and it was even worse than his original thin corroded wire of his margalla, I redid it with fresh wire and a real tinned copper lug crimped with a proper actual tool.
