Pearl white coupe revival

Shame you can't get euro bumpers, so much easier to work with, and way lighter/easier to remove.

While i much prefer the look of euro bumpers, i'd prefer not to eat the engine in a crash! A burly aluminum bar is a nice thing to have in an environment of terrible drivers in the land of SUVs and pickups!

at any rate....

and the state of the workshop as a result.... much cleaning to do now!!!!

Great progress, that's quite a moment eh?

[ottawa coupe]

It was definitely a bit of relief! A bit of a sidequest at the moment but i think this whole cnc mill thing has a bit of potential....

This is only the second attempt at machining ever... not terrible...

Still soooooo much to learn....

Will play with the mill for a while and atcthe same time, need to merge the wiring harnesses from the cabby and coupe.

Nice work! It almost looks like a whole car again! lol

[ottawa coupe]

Due to my bank accounts christmas annihilation, the cnc learning curve has to take a break for a coupla pay cycles..... So, the next nightmare begins. Wiring integration.

the broad strokes i with will be to replace the cabby body harness with the coupe one and remove the wiring for the automatic trans. The devil will be in figuring out how they did that originally and how to replicate it with what i have. I do have the offucial cabby wiring diagrams but the coupe ones are an amalagamation of bits i could find. Hopefully enough to cobble all of this together.

lotsa space on the floor to sort it out at least

I'm looking forward to seeing how you get on.

I also need to tackle the wiring on my car too!

Jase.

Well, wiring is not too terrible so far. Got the autotragic removed from cabby and i believe have the starter circuitry sorted, got the diff lock separated from the coupe abs wiring and ready to transplant into cabby harness. Got the coupe body harness removed from the fuse block. It is a bit of a mess though, i may have to use the cabby harness for at least part of it. We'll see how well it cleans up and how many broken wires there are. I will also remove the seat heaters because we all know they'd be broken even if i did have them lol.

main target today is to separate the power roof wiring from the cabby harness and see what the differences are afterwards. That will determine if i will modify the cab harness to the coupe or xfer the whole thing.

my preference is to use as much as the cabby stuff as feasible as it is in MUCH better shape. They're only 3 years apart but either the materials are better on the cabby or somehow the coupe's storage situation degraded things. I am finding that the coupe's connectors are VERY brittle and have broken a few of them as a result.

Edit: spaghetti madness!!!

Right, potentially fateful decision made.

I have successfully removed the powered roof from cabby harness and separated the rear body harness from the cq.

I have decided that i will be opening the harnesses up in order to separate the functions. Seat heaters are gonna go, the powered cq seat harness is pretty chewed up but i need to transfer the power and grounds to the cabby harness, i am keeping the cabby central locking/alarm but the harness is taped into the rest of it so needs to be opened up and separated.

the remainibg question in my head is related to the windows. Schematically, the front windows are the same but i THINK physically the relays are in different locations. So i may be transferring cq window control as well.

a lot of unwrapping to be done.....

that said, this is one of the easier swaps i have done because at least the platforms are the same so a lot less interpretation of schematics is needed lol

Basically, trying to keep as much b4 as possible.

Edit: got some time today between meetings. Cq harness now com0letely separated and everything i need to remove from the cabby harness is out. All except for one last thing that will be a bit of a nightmare. Seat heating. Still on the fence. Will have to see how much it will cost me to get elements into the porsche seats. But if i don't keep them, it's gonna be a bit of a chore getting the wiring out of the cabby harness. No matter what though i need to separate the powered seat part from the cq seat harness as it has the proper guage wire to power the seat motors in the porsche seats. So, another night's worth of wire pulling but then i can actually put one harness together and start mending any breaks.

[ottawa coupe]

Late night last night that i am paying for today but i completed stripping out the cabby harness and separating functions from the cq harness that i am keeping. None of the scraps are getting thrown away though just in case lol.

This is what's left of the cab harness. I have a few repairs to make from the 90s-tastic alarm install lol.

20250106_192417.jpg

I only have 1/2 a roll of the fiber tape so there's gonna be a delay before i can complete the final harness. I will also rig up somethi g so that i can test the function as it will be infintely easier now to diagnose/fix now that it will be in the car!

The last thing i did last night was to swap the original speedo/odo and fuel guage into the b4 instrument cluster. This will keep the car's mileage accurate as well as the fuel guage.

At any rate, it will take a few days for the tape to arrive but hopefully this is all sorted by the end of the weekend.

[ottawa coupe]

Well poop, not done the cutting just yet. The reverse light switch connection went thru the auto trans harness on the cabby and the engine harness on the coupe. So now i have to dig it out of the (untill now) untouched (but unwanted when i tried to sell) 7a engine harness. The rear difficulty is the plastic harness covering in the engine bay, i doubt i will be able replicate that. Any suggestions?

[Jaswan]

Hi again mate.

Good work! It will be worth the faff.

Did you find any good/useful documentation or diagrams anywhere?

Cheers

Jase.

[ottawa coupe]

I got the cabrio diagrams from the erwin audi site. They are a bit messed up in that they weren't scanned to the right size in the pdf and i had to cut n paste the pictures page by page into a word doc..... time consuming lol. Same issue i found for my urs6. that site had no b3 docs at all though.

My coupe files are an amalgamation of stuff from s2 central and google searched posts on various forums. I have the full service manual and i would estimate about 90% of the wiring diagrams as a result.

[ottawa coupe]

Well, missed last weekend for completion of the wiring modifications because of a cold, but should make this weekend. I've got 4 wires to get connected between diff lock and abs, fix a few from the aftermarket alarm deletion, and then a whoooooooolllllleeee lotta wire taping to do.

[ottawa coupe]

Sigh, i hate wiring. The more i look, the more questions pop up lol.

Gone from 4 wires to 8 after examining things last night.

I think i have most of my questions answered, just gotta actually get the soldering done now.

One bit of good news though, i figured out the bluetooth module for the tape deck. So i will forego radio (because it sucks here!) And will have a seamless integration to my phone now. I'll weld up the antenna hole in the spring. Smooooove.
