I attached the wiring diagrams from Ford on the transmission. Let me know if you need more info and we can get it for you. Thanks

FYI - The neutral safety switch on an automatic is called a digital transmission range sensor. Others call it a transmission position switch or just a range sensor.

I have a 92 f-250 7.3L diesel and the wiring harness from the transmission somehow got wrapped around the axle and pulled some of the wires out of place. I can not find this particular wiring diagram anywhere is there any place that it can be located.

Thanks!

the salvage yard matched it up for me. It has a 5.0l engine. maybe the range sensor is messed up or the wrong one.

I just need a diagram so I can see what I have. Can you help?

I found out whats going on but not shure whats causing it. the engine is only running on 4 cylinders at times. The computers ground pulse is cutting out on cylinders 2, 3, 6, and 7. This is all happened when I put the transmission in. Truck runs bad now, Any ideas to further troubleshoot this problem?

I forgot to mention that it was the fuel injectors that are not being driven by computer.

those cylinders are ground bank #2 from computer the other 4 cylinders are bank 1. check output right at computer pin 69 (white wire) next to it is pin 68 (tan wire bank #1) if good wiring/connections are suspect.
