Re: Audi A3 Hill Climb car
did you chose those chrome and plastic connectors? 8STA's are so much smaller and lighter!

No, that's what was recommended.

8STA's have an associated price tag though haha, there's a balance right

Those bits are automotive porn
I see you have traction knob pot, I'd recommend using another pot so you can set start line rpm also?

Re: Audi A3 Hill Climb car
Good idea, thanks Rob.
I spent a chunk of this weekend on the loom, and it's now completely disconnected. The only connectors not still connected to the loom were the two knock sensors, everything else came off without too much hassle. I did have to unbolt the entire steering column from the bulkhead to get the loom out.
This is what an entire Audi A3 loom looks like on the floor of the car:
Engine bay with no wiring left:
I'll pull the bits off I need over the next couple of evenings.
The engine loom up to the bulkhead is nearly ready, the connectors for the coils and cam sensor are now here. I just need to work out the pin outs.
Once that's done and fitted, I'll work out where the ECUs are going, and then run the interior cables.

Re: Audi A3 Hill Climb car
Wiring in modern cars is mental !
What sort of weight is it all ?

Re: Audi A3 Hill Climb car
It's ridiculous. What makes it worse is that everything is interlinked, so it's not even modular, virtually the whole lot is joined together.
Dunno yet, it's still in the car. I'm going to try and weigh it today.

Re: Audi A3 Hill Climb car
You do often wonder how the cars are built at the factory...when they are installing it, it must be easy for them.
And if it isnt, it must be costing the manufacturer a fortune in wasted time !

Re: Audi A3 Hill Climb car
This loom weighs close on 15kg. Now to strip out the 300g I need. I probably should have done a better job of marking the bits I need...
I've also test mounted the paddles and buttons on the steering wheel. I need to lengthen two wires, and connect the paddles to the rest of the loom.

Re: Audi A3 Hill Climb car
I made a good bit of progress on the wiring this weekend.
On Friday night, I started on the loom from the bulkhead to the ECU. It looked like this after a couple of hours in front of the TV:
At this point, I ran out of one of the contacts going in to the Souriau connector. I still need to run the connections to the STC which will add another ECU connector.
I've not heatshrunk it yet, as I want to make sure it's correct. I'll then take it apart, and tidy it up.
This morning I did a trial fitting of all the wiring. It went pretty well, I've got most of the lengths close enough.
Engine loom:
Weighs 0.75kg.
ECU rough location:
Engine loom test fit:
Interior loom test fit:
The interior loom is back out, so I can add the connectors required from the loom. There are a couple I need to work the wiring out on, like which is the brake light pin, why there are 4 wires from the alternator, and which starter motor wires are which, but this feels like a big step forward.
I need to work out where to fit the switch panel. I need to be able to reach it. I'd like to be able to fit a passenger seat, so that rules out just fitting it next to me on the passenger side. Some thinking required.
I also drilled out and removed the ignition barrel and housing, as I don't need the key, and the steering lock was still connected.
