Audi Coupe Quattro 2.3 20V - Czech Republic

[B5NUT]

I had a spare connector in my harness. The colour was brown and black.

Another set of hands will be useful . Many thanks, Brent your tips were really helpful
Folks, do you know where this connection should be connected? I assume fuse panel, but i can't find where exactly. Could someone please point where this belongs? Its a red Brown wire from that bundle.

Nice work on getting that 7A harness out in one piece. Can be tough without and extra set of hands to help.

I am happy that my car didn't burned as well and it ends only up with a meltdown connector, so I know how you feel. People who did this should be banned for life to work on cars.

My aftermarket alarm had a meltdown and nearly set fire to my car so had it all removed, there was a bin liner full of wiring and nonsense

Finally, the stock 7A engine harness is out. It was a really PITA job as I was on this on my own, but it's done. Now, I have to check and mark a little bit more some wires and after this, I have to think about how I will route the new custom engine harness together with the battery feed to the fuse box and things that will stay. Maybe I will rework connections that should stay.
I also start to rework some "******" connections which were there. I am using open barrel splices.

The battery wire for the fuse box should keep
The alternator wire should keep
Oil temp for AUX gauges should keep
The starter wire should keep
Wires for the fuse box (Engine control)

Thanks I won't install any alarm or immo or any audio I like the sound of 5 cylinder, so most of the time I have my radio turned off Now I have to redo these joints and after that, i have to remove the 7a engine harness, and to be honest, I am a little bit scared

Good work Tom!

Somewhere here on the forum there's pics of the pile of wiring and junk I removed from my coupe. 2 alarms, a tracker, a stereo install with 4 separate amps under the dash, and a bunch of stuff I didn't even understand, like a box with wires connecting to all the centre console switches!
In all several kilos of wire and a pile of boxes of electronics.
A lot of work to make good the looms but it's worth it, the alarms often break the feed to the fuel pump and ignition circuits with wire gauge and relays not capable of carrying the current, guaranteed to leave you stranded at some point.

[Tom_]

Thanks Hopefully, guys like him won't be working on the cars anymore as this could be pretty dangerous.

[psiconauta911]

I bet the guy that did that tried first with a hammer.
Like your thread!

[Tom_]

Honestly, I do not understand why someone could make this type of joint in the wiring. It's really disgusting and I don't really understand it. It looks like all wires are removed, now I am waiting for the open barrel splice crimper tool and once I get it, I will start to redo these ****** joints and make them properly.

[Tom_]

Thanks Brent, yeah, the wiring job so far is the hardest job so far. It's sad, that the official Audi factory manual cant be bought. There are a lot of useful information.

[jbrentd]

Sorry for missing your thread Tom. Great work! That's quite a mess with that old alarm system.

Keep posting those updates. I prefer the forums to FB.

[Tom_]

Today, I removed thé old flashpoint alarm/Central system. I was really shocked how joints/splices were made. Lots of twisted wires together only with some electric tape.
I assume that this aint from factory. Cant say if the central locking Will work after this removing :⁠-⁠D but ať least Its a fresh start to keep OEM locking system.

Folks, does someone have a stock anti theft system in the car? In coupe should be in the trunk.
