454 TBI and 4L80 from 95 burb into 69 van

Not sure I ever introduced myself....
I'm AzDon
I'm going to attempt to put a 454 and 4L80 from a 95 Suburban into a 69 van and make it run
As far as I can tell, there are no aftermarket harnesses available to do this, so I'm going to have to work the original Harness...
Wish me luck!

I went to a local yard that had a 95 7427 454 4l80e truck and told them I wanted the complete harness and they pulled it out for $75. Sorry maybe I missread. Looks like you have an original harness. I thought you were talkng about reworking the old harness.

Yeah, I have the entire donor Suburban...… Three problems I have using the original harness... 1) Knowing how much of it to remove from the car and knowing how to tie the existing car's controls into the harness … 2)Knowing what can be eliminated from the original harness.... and 3) Getting the harness without breaking all those fragile connectors or their latches....

To me, $300-500 is a bargain to get new stuff and some help/direction to making it happen.... It's when the stuff takes me past a Grand that I start looking at retreating to non-digital solutions...

I'm a little overwhelmed by the complexity of most of the stuff in these forums..... What I'm looking for is a simple, complete how-to that will direct me to get all the stuff needed from a 95 burb (454/4L80) into my 69 chevy van and wired up to run..... I'm not going to use the suburban instrument panel or ignition switch, so i'm a bit confused about how much of the stock harness to save and where to tie-in inputs/outputs for gauges and such and what the values should be. If it would be easier, I'd be willing to strip out the gauge wiring and put in standalone aftermarket stuff, even maybe mechanical... Does the whole thing begin with building some type of power/relay center and maybe centralizing all the grounds? Am I overthinking this? I know I'm about 20 years late to the party, but....
