The trigger wire still run off of fuses 7 & 8 for my 289fia...is it still ok to take power for the relay from fuse 7 or 8 to power the relay/headlights.
Life might be easier and simpler if I take the ammeter out.

That's just a case of confusing verbiage. We are not running
through the fuse box. When someone says
"take the power off the fuse box" that doesn't necessarily mean the
fused side of one of the fuses, rather it refers to a nice easy convenient feed that is usually half way between the alternator and the battery. If you are staring at the two ERA fuse boxes, the one on the passenger side of the car is the first box. The top fuse of that box, on the passenger side of the fuse, is a direct feed from the alternator (and the fused side of that fuse runs to the fans). If you just tap that passenger side screw, it will always be hot, and it is unfused. So, whatever you run from a tap from that screw must have an inline fuse, or circuit breaker, to protect it. That's all the phrase means.
