Fuse/relay panel location 98 kw w900l

Open the gauge panel and switch panel to the right of your speedometer. The engine fan relay is in there. You will have to dig around to find it , not mounted , it just lays in there towards the bottom.

 

Fire your "mechanic".

 

I have a W900B that the former owner moved the fan relay to the upper firewall on the engine side for what it's worth.

 

remove the panels to the right of those , temp gauge panel and the switch panel next to it. Trust me the relay is there , it will be buried under a lot of air lines and wires

 

It's called SIS. Fire your mechanic. Actually, my mistake. SIS is for CAT. This is indeed a KW diagram issue. If they can't find it by looking up your VIN than why not just run a new fused power wire and be done with it?

 

The diagram of the harness is no longer available K068-6648, but relay is part of the Cummins in cab harness. The fuse panel was designed before electronic engines, so add on harness were used for Cat, Cummins, or Detroit engines. I attached the diagram in your other thread. The diagrams calls out the wire #, color, and gauge. Find it that way. Most likely stuffed in behind gauges somewhere, been along time since I worked on one with a Cummins.
