Fox starter solenoid power connections question

[Boostedpimp]

What has everyone done with there starter solenoid in terms of power attachments? I've ran out of real estate on the bolt thread for all the components.

Just have the typical connections like the Circuit breaker for windows/doors, the yellow wire, the green wire, the blue wire, the starter power wire and battery positive cable. Cant fit the efan, or 3g alternator without it being a total hack job which i'm not good with.

So how has everyone dealt with this with there cars?

I was thinking of mounting a junction box or terminal on the backside of the battery tray or out of sight in the fender for the big stuff and just run one wire from that back to the solenoid but what gauge wire would I need for this?

Engine bays dirty and incomplete but i'll include a picture because I hate threads without pictures

Latter 80s to early 90s chevy full size trucks have a power bulkhead near the center of the firewall under the hood. It's usually under a plastic cover. It bolts on with two small bolts. It'll give you 5 more power connections.
