I'm not sure what the black wire with the blue strain reliefs is for... It's not stock looking. I'd cover up the loose end or remove the hot end from the J block. If that loose terminal shorts against something it'll blow the fusible link at the starter.

Hey, would you mind elaborating what you mean by easy? Cause I had my wiring guy look at the chilton for nearly 2 hours and it dont show the junction block.

Is there more diagrams some where?

Thanks.

85 Manual should be pretty close, only major difference would be the sensors on the box fuel filter.
You have the round type so that wouldn't matter, no sensors, less wires to worry about

81 & 82 wiring is in the back of the service manual PDFs... They were broken up by Helm into 8.5" x 11" pages instead of the nice 11"x 38" foldouts.
83 glowplugs are the same. The rest should be very close with the exception of the cruise control system.

GM diagrams are much better than the generic fits-all Chilton or Haynes diagrams. If you can find a 1982 Motor domestic truck wiring and vacuum diagram manual... It will come close to the factory diagrams but they're pretty pricey for close.
