408 wont run

looks like you can eliminate the dark blue wit all together, then connect the light blue (which should be hot in run) to both browns and the green/red
(you are feeding all of them with the blue one)

or...if you want it to look real spiffy, remove the ballast resistor from the firewall and gut it from the back
once the space connectors are exposed, solder jumper wires in place of the resistors and bolt it back on

that way it will even look stock

(it was a little easier with my 2 prong resistor)
