Does anyone know where to locate the ignition switch in a '85 El Camino and how to replace it as well?

Its in the column, you need to remove the steering wheel, dig deeper into the column, take the turn signal cam out and hazard button and stuff like that, probably 30 screwes and bolts along the way, eventually you can get the switch out.

can seem like a daunting task but once you do it yourself its easy.

Dont mean to send you to another forum but here is a great walk through with pictures. enjoy
