Insert them and push with pliers as far as they go

if your radio is for example audi chorus/concert1, ground pin for CD changer is on 10pin connector on this picture, upper right, but body for this connector is to expensive for low budget project like this emu, so ground connection is made by cable fastened to metal chassis of radio. Screw has torx T-9 head.
