With the switch in the RUN position, push the cylinder in with the key inserted and turn. Sometimes it helps to press up the release button.

ya that's what i'm tying and it just doesn't want to click in. i know the switches changed over the years. but did the cylinder change at all. i'm wondering if it's not the correct cylinder?

D8TZ-11582-A .. Ignition Cylinder w/keys (Motorcraft SW-1517).

1978 F100/880 & Bronco from serial number CA0,001 / 1979 F100/880 & Bronco.

There are THREE different ignition switches: 1970/76; 1977; 1978/79.

Compare the original switch and cylinder with the new parts.
