89 200 tqa - fuse box connectors + wire help

[Samir Shah <gofast1@home.com>]

Yesterday, I dismantled the 200's interior, drilled out the rusty screws
that were holding the carpet in, and snaked over the new 10 gauge
positive wires to right below the fuse box. Now, I need some advice and
help.

a) There is not enough play in the fuse box wires to pull it up from the
engine compartment side, so I have not yet gotten a look at the wire
connector. Looking at the Bentley, it appears that these 2 wires from
the battery go to connector L/track 30 under the fuse box. I'll probably
need to go in from underneath, and wade my way through the spaghetti
under the dash.

- Does anyone know what kind of crimps I need to install on the new
wires, and if they are available at the dealer. Any part numbers?
- Do I need a special tool to get the wires out from the connector
block?
- Should I leave the connector connected, and just splice the new wires
to the old wires?

b) As mentioned above, I used 10 gauge wire, based on a piece of the old
wire I showed the guy at NAPA. Looking at the manual, it appears that
Audi's wire is an 8 gauge equivalent. Is this going to cause a problem?
Its not look late to change wires, (but so far I've not found 8 gauge at
any of the local stores - will need to hunt a bit, I guess). Or I could
run a third 10 gauge wire and join them.  As I mentioned in a previous
post, the Audi wire was getting hot, but the 6 inches or so of new 10
gauge wire was not, so at the very least, this should have less
resistance that the old wire.

Thanks in advance. Samir.
