Fitting an after market radio cables is pretty easy to do.
This is a guide to the cables.
So I had to purchase a VW - ISO one from eBay, pretty easy done also a radio cable adaptor as the aerial is completely different. i will post links to everything i have purchased tomorrow.
Sorry the first shot is a bit blurred but it shows the two cables
As the rear speakers in the doors are not going to go via the loom of the car I have blanked them off and heat sealed them.
All the other cables are joint and heat sealed too.
Easy to check your cables are right by plugging the two ends into each other and then you can check the wiring. If you get one speaker the wrong way round it will be out of phase and sound shocking
The plastic fitting is the next part on the way. This bit and the rear wires is a bit iffy especially as the plastic can be cheap and the metal clips can come loose.
