Hi everyone, i recently took my bootlid off with the spoiler an changed the boot to no spoiler on my ef fairmont

now i cut the wire going to the bootlid brake light and now want to get the interior brake light to work.

just wondering how re wire it so the light on the parcel shelf works

Does the parcel shelf brake light have black plastic in it or does it have the red clear plastic? Just check by looking through the back window.
If it has the black plastic you'll need to remove it and replace with the red clear.

If it has the black plastic in it that indicates the spoiler was factory fitted. If it is red then its dealer fitted or after market.
