89 coupe digital Speedo w/ hud

[Jays13coupe]

What's up fellow drifters ,

I've been looking at discussions oin zilvia for a long time now, but just finally joined site.

Now i know there's been some to many discussions on the digital hud cluster and it's many mysteries& problems.. don't mean to beat a dead horse, I know most ppls 2 cents would be go to analog cluster, i don't wnt to do that, but I'd appreciate other helpful info.

Here's my deal tho.
I am on my 5th s13 ( besides parts cars I've had) did auto to 5 speed swap to it by myself.
It's the first coupe I've had and the first digital cluster I've had.

The digital Speedo / hud and odometer / trip has never once lit up or worked for me. ( drove it for 3 yrs as auto , so I know it's not swap related)
I finally bought a second digital cluster, put it in and nothing still,
I did how ever find that the sub harness for instrument cluster had been tampered with by previous owner,
I've been been trying to figure this whole thing out for about 5 yrs now lol, ( pathetic I just saw the wires being spliced )

Getting to the point,

I'm in need of detailed digital sub harness pics,
Or
If anyone has same set up in my area I'd pay for ur time to bring ur car over to mine and let me check out how out need too be wired.
Or
Or to buy one if anyone has one that's legit,

I'd appreciate any INFO ,
Thank u.

I live in Sonoma county,
