Door Wiring
Now to tackle the new door wiring. Disconnect the large connector near the door hinge by pulling up the blue clip and seperating the connector.

Remove the socket from the door by pushing the 2 tabs on the top and bottom of the socket and pushing the socket into the door.

The unclip all the wiring and remove the loom from the door. Here you can see the size of the old loom (top) compared to the new one (bottom.) The new loom has extra cabling for the cental locking and electric window (not used in our case, so this section of wiring can be cut if you wish - its the only other 2 pin connector that isn't for the door speaker or tweeter.)

Then install the new loom into the door, connecting the central locking motor. There will be holes already pre-cut into the door for all the wiring clips. You will notice I have left the electric window connector in place incase I want to install them at a later date - I just clipped the connector to the door metalwork to stop it rattling while driving. Push the large connector back into the hole in the door by the hinge and it will click securely into place.

Then refit the protective sheet - remember to tape up any tears, and use some sealent if the sheet won't stick back into place.

Refit the doorcard and all its fittings, and connect the door back up to the car at the door hinge.

Test the radio to ensure the speaker and tweeter are both still working. Also test the lock with the key, by locking it with the door pin, and that both inner and outer door handles are working.
Then do it all over again on the other door!
