I just got an Alpine head unit 9880R, and reading through these forums I now know I need to change the red and yellow wires around, and to take out K3? cable so I dont damage any vag tools via the diagnostics.

The questions I have are:

Is it easy to swap the red and yellow cables over or is it a case of block connector to change them over?

The K3 cable is this easy to take out or is a cut and terminate job?

I brought the ariel booster cable with the blue power cable, where does this plug into? power ariel cable?

Thanks for your help.

think i found the ariel advice I need plug ariel into blue remote cable out of headunit.

Anyone for the other bits? I see loads have replaced their HU!! :-S

No experience with these cars - but most head units let you swap the red and yellow wires at the loom provided on the HU, either with bullet connectors, or pins that can easily be swapped around in the ISO connector.

yeh you were totally right, the iso allowed this and the k3 pin isnt used so all good, was real tight getting in there with all the cables but I managed it, must admit now I have it in I might consider changing the conponent speakers in the front soon!
