Heres a quick shot of my original fuse/relay panel.
Off to jaycar tomorrow to arm up for a better go at it.
With most relays, flasher unit being mounted together, it will double in size/complexity. I have a few wiring diagrams and use early 90s' mx5 diagrams as inspiration for simplicity. I discovered early rx7s' didn't use relays in their power window circuits instead flowing full amperage through uprated switches. Hmmm theres an idea...
