The MPS Weeded and Labeled Holley EFI Harness (p/n 1-0676) gives you a great start to a custom harness. They have all the excess wires removed that are not needed and have the sensor power and grounds added for each sensor. We then label each set of sensor leads. All the sensor connectors except the actual ECU plugs must be installed by the end user.
