Simply remove the setup from the box and install it on the car.

About the Hideaway Harness Option:

  • This harness uses the same high quality connectors, military spec tefzel wire, and wire sheath as our standard COP wire harness, but this one hides under the mounting plate for a super clean, wire tucked look! This harness offers the same quality and performance as you'd expect from any product offered by JD Customs USA. This harness is sold separately, or can be added to any of our ignition system options for an additional $30. 

How is this harness different?

  • Both leads come out from the valve cover on the right side and are concealed by a single wire sheath. The right side connector makes its hidden connection behind the thermostat housing and the left side lead can be ran under or over the intake manifold to make its connection behind the valve cover for another hidden connection.
