Thanks for the wiring diagram Barkfast. That is some nice insight. I did a search and found the following regarding the cross over grounding:
Quote:
The reason the ground for indicator flasher cans alternates between the side that is activated and the side that is not is due to the design of the turn signal circuit, which often grounds the flasher through the alternate side bulbs via the indicator light. This setup allows the flasher to utilize the current drawn by the bulbs to regulate the flashing cycle. Essentially, the flasher relies on the resistance of the bulbs to determine the flash rate, and this is managed by switching on the ground side rather than the power side.
In this configuration, when one side's turn signal is activated, the flasher grounds through the bulbs on the opposite side, ensuring the indicator light flashes in sync with the activated turn signal. This method helps in maintaining the correct flash rate and ensures the indicator light operates correctly without requiring a separate ground for each side
I ordered my bulbs and flasher from Aliepxress, all up total, including front park indicator (white/white), rear indicator (yellow), rear brake&park (red/red), LED flasher can and number plate lamps was 15 dollars
