Looking for additional unfused ignition locations

[imholte]

I have a 72 k10 and just put in a new aluminum radiator and am working on the dual spal fan install.

The install instructions have a connection to the keyed ignition power. No problem I will just run it to the fusebox and put it to one of the unfused igniton tabs (with a inline fuse). When I get there I see that I used both of the unfused ignition tabs for the HEI and the Echoke on the weber carb (I think, its been 10 years since i put that in).

So the big question is can I just tie in to one of the wires leaving the box for the HEI or carb choke or is there a better way to do it.

The new radiator and fan look great but then when compared to everything else it looks pretty bad.
