      • Each Part Number Is Fully Assembled, Taped And Ready To Install Upon Arrival
      • This Harness Will Plug Into The Firewall In The Factory Location, And Will Follow Original Routing In The Engine Compartment
      • A Combination Of The Engine And Front Light Harness Accomplish Most Functions Under The Hood Of An Early GM Vehicle
      • Engine Harness Design Varied Significantly From Year To Year, But Most Will Contain Wiring For Ignition System, Starter, Heater Blower, And Temperature/Oil Pressure Sender Wires If Applicable
      • Some Vehicles Used A Capillary Tube To Provide An Oil Pressure Reading, So These Will Not Be Included In A Wiring Harness
      • On Vehicles With Ignition Points, The Circuit Feeding The Ignition Coil Was Designed With Some Resistance To Extend The Life Of The Ignition Point Set
      • Modern Electronic Ignition Systems Or High Energy Ignition (HEI) Systems Do Not Require Resistance In The Circuit; It Is Recommended That A Harness Modified For HEI Be Ordered If Ignition System Has Been Upgraded
      • Please Consult Your Factory Service Manual To Determine If The Engine Harness For Your Vehicle Will Contain The Circuits Required For Your Project, Or Contact The Sales Team To Confirm Part Numbers
