LED resistor in front signal circuit.....where???

Post by Dayne66 »

I looked at the schematic in the Haynes manual....just at the 'left front park/turn lamp'......LT Blue and Black go to the signal.....installed Phillips 21W across these two wires... and still have hyper-flash .

So...I look at the schematic again......how does the marker light run of off the Lt Blu and the BRN....2 positives???

Will a LED flasher solve the hyper flash?
