The easiest way to do it is just get the civic plugs and use a dual filament bulb from a civic tap one side to your turn signal and the other to the wires that are on the stock accord.

So for instance civic plug has red black and green wires
Accord has black and red

Cut off the accord plug and take the civic plug and the accord exposed wires and put the red wires together and the black wires together for the third wire find the hot wire on the parking light and then tap the green wire to the hot wire in the parking light and bam done
