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)

If so I agree with your simple schematic. (IMG:style_emoticons/default/smile.gif) I did this same thing with my custom EFI system. Various signals can turn on the "check engine" light. |
