Pictured here is the BASE level k series engine harness, not to be confused with a base trim chassis. Base level engine harnesses will be used to refer to base pricing. Engine harness will come pre wired for swap vehicles,fan switch and temp switch connectors will be placed at the thermostat housing location. Engine harnesses are more designed for swap chassis but can be used on stock 02-04 RSX type S but will require a slight mod. if you plan to use an RSX chassis please let me know and i can make the needed mod. Oil pressure switch and temp switch will now feature actual connector housings (see last picture), no heat shrink covered bullet connectors. This added feature helps to ensure the they don’t get loose and easier and safer to grab when removing.
