eyeball my MSD box & 2 step wiring.

[04ctd]

gonna put this tray on hinges.




so that it tucks up under the dash when not used,
but you can fold it down to work on it.
the long ground strap is from the case, to chassis grounds, eliminates any chance of a floating ground or static charge


I did a power distro block on the firewall:
I moved the smaller wires off the starter, and ran one big wire up to a large car stereo fuse on the firewall, and made that a +12v wiring center with fuses



I came off there, and went under the dash, and made a hinged panel,
with 2 blocks:
one is hot/battery,
one is switched/accessory.



i just put a relay on back of it, and used the accessory lead for the radio to cycle the relay.
