Wiring looms

Sometimes the most overlooked, forgotten, or avoided aspect of build a custom motorcycle has to be the electrical system, At Second City Customs we specialise in motorcycle electrical and wiring systems and can design and manufacture a bespoke loom to suit your motorcycle.

At Second City Customs we are more than happy to tackle all of your custom wiring needs! Do you want a slimline harness for your custom Bobber? or a simplifed wiring loom for your new cafe racer? we can handle it no problem. 

All of our wiring looms are designed from scratch and hand built onto your bike, made with brand new wiring using UK manufactured thin wall cable or for a more classic look we can use authentic braided cloth cable which has the look of original but the electical and mecahnical properties of modern cable.All cable connectors are soldered together so they are less likely to cause and problems in the future and fianlly the loom is covered in either braided sheathing, High quality PVC or Cloth tape to give that OEM look

For prices please contact us as each job is unique to the bike and your requirements.



We have the latest diagnostic equipment for Harley Davidson motorcycles and can carry out upgrades and full fault code diagnostics.

If you have changed or was thinking of upgrading you brake lines on models with ABS we can also bleed the brakes correctly.
