Those families have separate harness kit references, including 888311 in the related catalogue context.

Compare the complete part number, model year, ES\/KS system, digital or analogue meter, tail-light routing, fuse-box arrangement, connector count, wire lengths and the original harness before ordering.\u003c\/p\u003e\n\u003ch3\u003eCan I splice or modify 888315 to make it fit?\u003c\/h3\u003e\n\u003cp\u003eDo not splice, cut, extend, repin or modify the harness to force fitment. An incorrect wiring change can cause short circuits, electrical damage, unreliable lighting or fire risk.

Diagnose the battery, switches, relays, fuses, grounds, lamps and charging system before replacing the harness.\u003c\/p\u003e\n\u003ch3\u003eWill 888315 fix a no-start problem?\u003c\/h3\u003e\n\u003cp\u003eNot necessarily.
