Rewiring my EFI Magnum - 1970 Dart Swinger

I'll be running all the extra wires through the hole that's for the manual washer pump. I got a big grommet to keep the wire insulation happy, and I'll be putting connectors on everything, as opposed to hardwiring, so I can pull it apart and easily put it back together if I have to.

I bought these knock-off Deutsch Connectors and I'm really happy with them. They will be on the other side of the grommet inside the cabin so weatherproofing is not really necessary, but I needed something that would support 10 wires and fit through the 1 3/8 inch hold in the firewall. The 8 pin and 4 pin connectors from the kit are perfect.
