New to the forum, looks like there's alot of helpful posters!
I'm having a lot of trouble figuring out which adapters I need to connect my new HU, replacing the Chorus.
Car is an A3, 2002. There's a sub in the boot compartment. I'm not sure if the system is bose or not, and whether its rear or fully amped.
New HU is Pioneer DEH-P4100SD
I got PC9-404 connecter which I thought was correct.
And PC5-90 which looks correct.
I connected these & played around with the connections but unit wouldn't power on.
Looking at the PC9-404 adapter. I don't see what it actually does, it seems like an extension as the wiring is the same at both ends. The blocks coming from the car don't match up to the input of the cable.
The red connector doesn't match up either as it only has 4 inputs where the block from the car has 6 wires. I think this means it's a bose system?
The pioneer unit has an RCA input (so red adapter can go here?) and was supplied with an adapter which takes 2 blocks input.
I've attached pictures so maybe somebody can recognise the system & whats needed?
I'd really appreciate some help!
1. 2 blocks from car system (power & L/R speakers?)
2. Block from car system to connect to red adapter & RCA
3. Adapter supplied with Pioneer HU
4. Adapter close up
