Changing an Linn amp from Aktiv back to passive

I have a LK100 with aktiv treble cards for Keilidh speakers. Each card connects to the board by way of a male (4-pin) connector that attaches to a female multi-wire (I think four wire) connector wired off the main board. The female connector (I think for the right channel) has a green wire that looks to have been cut and spliced onto a same-color green wire coming off the board. The other card connector does the same, but with a yellow wire. Does anyone know what I need to do, after removing the cards by pulling the female off the male part of the card, to make the amp work passively again? It looks like the green and yellow wire coming off the board and spiced need to be reattached somewhere.

Thanks,
Dave
