Factory Replacement Style Dash Harnesses with ATO Type Fuse Blocks

No cutting, modifying or altering of any sort required

Our new Classic Auto Fuse Series Dash Harnesses allow the professional restorer to maintain the plug and play functionality of the original factory type harnesses, while converting the entire fuse block to an Auto Fuse Series (ATO Type) fuse block. The Classic Auto Fuse Series Dash Harnesses give restorers the flexibility to add additional power circuits, without the installation headaches normally associated with this type of fuse box conversion.

The plug and play Classic Auto Fuse Series Dash Harness are a first in the industry. Don’t be fooled by clever advertising and claims by others that their do-it-yourself harnesses are easy to install. There is no other product like this on the market, anywhere.

There is no cutting, modifying or altering of any sort required. Just plug it in and turn it on, it’s that simple. The Classic Auto Fuse Dash Harnesses are completely compatible with the remaining harnesses in the car; couple that with our world renowned Free technical support for the finest product money can buy.

ATO Type Fuse Block

ATO Type Fuse Block with additional, fully integrated power ports allows the restorer to easily tap power for aftermarket electronic devices such as electric radiator fans, fuel pumps & ignition boxes.

Original Factory Bulkhead Connector

An Original Factory Bulkhead Connector is used on the back of the ATO Fuse Block. This allows the restorer to maintain the plug & play functionality of factory original style Engine & Forward Harnesses.

GXL Wire & OEM Connectors

We use U.S.A. made GXL wire which is much more tolerant to heat than the original GPT type wire that was used from the factory. Wire colors match the original factory specs, as does every connector and terminal.
