Possible by using two steering diodes. I believe 1N4001 diodes will support 1 amp. Should be more than enough for a small indicator lamp.
Jim, one power from relay ( black/yellow), other from fan. Tom Attached thumbnail(s)

Had me baffled for a moment, then I decided you meant "EGR", not "ERG". Since you no longer have an EGR, why not just wire the light directly to the source you'll be monitoring?
