fried wires

OK awesome help guys thank you all. Sorry, I thought it was assumed to be my 81 step slant d150. I work at a local dealership in the service department as a service writer so I asked a friend(master tech). He helped me find the issue.

Issue was:
I removed the spark control computer. Then removed egr crud and left a pig tail loose. Mind you the truck has been running for weeks like this with no issues what so ever. This pigtail ground out on the engine block and fried it and ran all the way through the passenger side large wire harness connection all the way to the fusible links on the driver side fender well. The blue wire there. I hooked that back up and that's how I overheated the blue wire under the steering column. After we inspected the entire wire harness we learned all this. I was show where and how and what I did wrong when I taped back up the harness after putting the Hei in and removing egr vacuum crud.



Thank you for the help. I have a volt gauge that is not installed yet. I am planning on replacing the wire and going through the entire harness when out of its tape and repairing any and all wiring properly. I just need to wait until payday Friday.

Thank you all again. I got a car to drive from work thankfully but I need to get this done ASAP so my question is any recommendations on how to make this simple easy safe and fast?
