STOCK HARNESS OUT OF VEHICLE IS REQUIRED TO BE SENT IN. THIS IS THE HARNESS THAT YOU ARE INSTALLING YOUR NEW ENGINE INTO. IF YOU DO NOT HAVE A DONOR HARNESS AVAILABLE PLEASE SELECT ADD CORE HARNESS AT CHECKOUT.

OUR DIRECT-FIT HARNESSES ARE BUILT COMPLETELY CUSTOM TO YOUR ENGINE SPECIFICATIONS. THESE HARNESSES WILL RETAIN ALL FACTORY GAUGES, AIR CONDITIONING, ABS BRAKES AND CRUISE CONTROL WHERE APPLICABLE.

WHEN WE SAY CUSTOM BUILT WE MEAN IT. THE HARNESS WILL BE BUILT TO MATCH YOUR EXACT INJECTOR STYLE, MAP SENSOR, MASS AIR FLOW SENSOR ETC.

THE DIFFERENCE BETWEEN A DIRECT-FIT HARNESS AND A STAND-ALONE HARNESS IS THAT A DIRECT-FIT IS COMPLETELY PLUG AND PLAY JUST REINSTALL IN YOUR TRUCK AND TURN THE KEY, A STAND-ALONE WILL SIMPLY ALLOW THE ENGINE TO RUN BUT PROVIDES NO INTEGRATION INTO THE TRUCK ITSELF.

GEN 4 ENGINES WILL REQUIRE A FUEL-LINK FOR PROPER FUEL GAUGE CALIBRATION AND IF CRUISE CONTROL IS TO BE RETAINED WILL REQUIRE DAKOTA DIGITAL CRUISE CONTROL MODULE.

ALL HARNESSES COME WRAPPED IN A BRAIDED SLEEVING FOR THAT ONE OF A KIND SHOW FINISH.

NOTE: HARNESSES REQUIRE THE FOLLOWING SENSORS:

• 1-WIRE OIL PRESSURE SENSOR
• 3-WIRE COOLANT TEMP SENSOR

NOTE: THESE HARNESSES HAVE A LEAD TIME, PLEASE CHECK THE LEAD TIME PAGE LINK AT TOP FOR CURRENT LEAD TIMES

NOTE: DO NOT SEND IN ANY FACTORY COMPUTERS.

NOTE: THESE HARNESSES ARE NON-REFUNDABLE
