yes... could be nice too... One groove with the resistor, the other groove with the diode. Just would need just to jump out on dual ballast plugs on both sides. Blue wire is already done actually from factory on existant dual ballast setups, just would need to jump the brown side between both prongs straight at the same plug like blue wires are already done.



This is of of course you are using a 4 pins ECU, not 5 pins. You would be sacrifing the secondary resistor what feeds the unexistant pin on 4 pins ECUs

and as mentioned ALLWAYS conecting same plugs on same side of ballast, never reversed like being just a resistor doesn't matter.
