I recently obtain diagrams for the VIN R series in reference to PCM pin outs. I should requested a Bulkhead connector pin outs diagram when I registered. The 2000 Chevrolet 2500 express van wiring harness VIN R series, would be fully functional however, the bulkhead Connector has got me stump. Dissembling the mate connector in the interior is a chore when I don't have knowledge which color wire orientates to their particular function. It's a 35 pin Connector starting A thru E. Each letter has 7 terminal cavities, A1 thru A7 and E1 thru E7. The last 3 terminals in A5, 6 and 7 are for heavy gauge wire and E1, 2 and 3 also with 3 red 10 gauge wires I know the first Connector I've seen from a1997 Silverado. And this is the 2000 Chevrolet 2500 express van. So this is the swap. I. Repinned the 4 connector PCM wires accordingly from the 97 Silverado harness to the 2000 express. Same motor's, PCM's and the bulkhead connector. But, again, I'm not a calculus teacher on wiring engineering and I appreciate this website has helped me in the past. My deepest appreciation is for the bulkhead connector pin outs for a 2000 Chevrolet 2500 Express Van. I'm disabled and on a fixed income so I can donate a small amount to this website. Thank you.

Let me know if this seems to match your connector. The only reason I am not sure is you said yours goes to A and E 7. This shows it goes to 8. However, this is what is listed as the bulkhead connector C100. I attached the location as well to make sure we are talking about the same one.

Let me know and we can go from there.

Lastly, you are very kind to offer a donation but this is a free website and we are here to help so no donation is needed. Thanks

Hey Kenny. Many, Many thanks. Yes. It was right on the money. I would have been totally lost without the two diagrams that I made into one. And the other 4 diagrams, I made into one also. Plus the 2made into one, I consolidated the 6 into one diagram.
I was almost done and completed with actual components for better visuals however windows 10 had a mind of it's over zealous police state and striped me out of all my personal pictures, graphics and documents. So my next reply is for the photoshop spectrum of all the diagrams into one I would like to share with you. I've already breaking ground on a new one since I have multiple desktops and operating systems Thanks again for having such a great website.
At least I can share with a car alarm diagram that was in Russian so I stripped the words to remake a new diagram for a PRESTIGE PLATINUM ASP-350. Sharing is because it's there.

Thanks for sharing. We have wiring diagrams as well so whenever you are working on something and need any info at all we can get pretty much anything that is provided by the OEM. We have access to Alldata and Mitchell so again, if you need something in the future just come back and start a post for it and we will reply to you. Thanks again.
