Lift Pump Relay Harness
A must have for all years of the 6.5L! This will take the load off your oil pressure switch and run two new, heavier gauge, wires to your factory or replacement lift pump to ensure it gets the steady power it needs to function reliably. We've also updated them to use a weatherproof, fused, relay.
*Please select the correct model when ordering due to variances in under-hood wiring configuration by model year
WTSP = Wait to Start Prime feature. All of our pre-1996 mode year harnesses include this feature now. 1996 and later don't require it since the fuel pump automatically primes when the key is turned on.
