I need to add a 6 circuit auxillary fuse block to my 69 and I'm needing suggestions on how to wire the source power in. I'm thinking I could run an 8 gauge wire from the firewall mounted starter relay but I would like to hear from others that have actually added an auxillary fuse block. I know I could souce the 12v directly from the trunk mounted battery or even on the starter solenoid. The alternator output stud in not an option for me because space is limited. The starter relay would be the most efficient location if there aren't any issues I'm not aware of. Thanks!!!
