454 TBI and 4L80 from 95 burb into 69 van

If you haven't done so, go to definitions on the first part of this obd1 forum and go to pcm 6395, $OE. Towards the bottom is 6 wiring diagrams. With that you have what you will need. You pretty well will use it all except gauges. You will need the drac, the check engine lite and the obd1 aldl port. For gauges you can just put in original senders for those. You will then be running the computer off the efi senders and gauges off old style senders. Ignition switch will just control a power relay. Of course there would be other ways to do it but this is pretty simple.

Thank you for the replies!.... I spent a couple of hours in the burb dash today working on deconstruction.... It looks like I'm going to need to pull the dash apart completely to get the complete harness......A while back I de-constructed a 91 wagon and pulled 100% of all wiring out and started verifying wires and routing and had the entire floor of the 2 car garage covered with wires....Decided to do it later when I installed the 305 into the van, but changed the plan to this 454...…..I guess the way to do it is to get the engine, trans, and necessary components in place and then lay the harness over the whole setup and start connecting and pruning (?)……. By the time I get to that point, I'll probably want to just buy that harness from fuel injection connection....
