Related question on the dash wiring: I want to use a single pole single throw switch to control the hazard lights, rather than the double pole double throw switch included in the kit. I believe this can be done by wiring one terminal on the switch to the hazard flasher and the other terminal to the lights on the four corners of the car. I also believe I'll need to incorporate a diode on the left and right side circuits. Can anyone please confirm this is correct? Thanks in advance.
