Behold before your eyes....a very old wiring loom. Wrapped in Japan by a Honda guru about 50 years ago...or maybe even more. Its a good bet the afore mentioned loom wrapper is no longer working at the Big H factory. Possible even that the dude is wrapping heavenly looms...
Would be a shame to destroy all his work so have reworked the Belgium Honda wiring sympathetically.. Hopefully you agree. Used Ford Anglia spec grey non adhesive loom wrap and stuck the ends with old skool Self amalgamating tape.

... Bling....Bling
