Do American Autowire kits work with EFI engines?

While American Autowire does not currently manufacture any EFI (Electronic Fuel Injection) engine management harnesses, our Classic Update, Highway, Builder, and Power Plus Series kits are directly compatible with most OEM and aftermarket engine management systems.  Generally speaking, most engine management wiring systems will only require two power sources that can be sourced directly from the fuse panels provided in our kits: a 12v keyed ignition power source and a direct battery powered source.
