Neutral position/ safety switch

2000 Express 3500 6.5 Turbo Diesel

Replaced safety switch 1 mo ago. Now same problem. Turn the key & nothing happens. I can start the truck by jumping out the pins at the starter relay under the hood in the fuse block.

My issue is that I need identification for the pins at the safety switch. My switch has a 7 pin and a 4 pin plug. I suspect the 4 pin is involved.

I have the chilton's online manual, but is shows little of this switch. Any help would be great.

Thanks for your quick response. The schematic was perfect, thank you. I found the right terminals and temp. fixed the connection at the switch. The harness is mangled, so I'll have to replace both plugs. After I fixed the connections and replaced a fuse in the inside panel, it started right up.

Thank you again.
Now I have to troubleshoot my glow plug circuit. The truck won't start in the cold without starting fluid, also a new problem.

You are welcome and thanks for posting back how it went.
Glad you got it figured out and fixed.

On the glow plugs always test each glow plug.
I always like to just touch a 12 volt fused jumper to each one and see if they are pulling voltage.
A bad or weak glow plug will not pull any voltage.
Good Luck
