ISO Adapter for Audi A3 Sportback 8P?

[HTR]

Hi all,

I have purchased a Kenwood Double-DIN headunit and are trying to source the correct ISO harness adapter lead?

I have used a VAG 'Quad-Lock' from my old MK5 Golf but this adapter misses out two connector blocks from the Audi cable - Also the rear speakers do not function with this lead (assume they run off one of these additional connector blocks?)

I have an A3 Sportback 8P currently with the standard 'Audi Concert' headunit.

Can anyone advise?

Assume your A3 was late 06 onwards to have quadlock fitted, so kenwood has iso, so you'd have to do a reverse adaption, so female quadlock to male iso's for the kenwood, think I got that right lol.

ebay or halfords should have these adaptors for sure mate.

Here's a concert wiring diag, assume top 2 are missing?
