Additional Notes:
- Used with 1967-1978 Chevy Truck Classic Auto Fuse Series ATO fuse type dash harnesses.
- Use caution when mounting on Classic Auto Fuse Series dash harnesses to ensure sufficient clearance is available to mount the relay connector(s) on the side of the fuse block containing the mounting ribs. In some applications, the relay and connector will not clear structural devices such as emergency brake pedal system brackets, etc. when the fuse block is installed. See direct fit dash harness instructions which have drawings showing the rib locations on the Classic Auto Fuse Series fuse blocks.
