The original vehicle wiring loom may not match the ISO plug used by the majority of aftermarket head unit manufacturers. Cutting the original vehicle wiring loom may invalidate the vehicle warranty. To overcome this difficulty, an Autoleads Harness Adaptor will plug directly into the vehicle wiring loom and configure it to an ISO plug, therefore removing the need to cut any wiring. A range of antenna adaptors is also available for vehicles with non-standard aerial connections.

When installing an aftermarket radio into your vehicle an adaptor lead is often required to enable connection of the vehicles existing aerial to the new head unit. Autoleads offer a fixing solution for the vast majority of vehicles.
