Hi Mike,
I saw this thread a while back and committed its existence (although not its valuable details) to memory for future reference. The reason is I've deleted the center console but found that the turn signals won't work without the flasher switch connected. And I've replaced my dash with the Rennline version so would like to incorporate a simple two-pole (with ground) aftermarket toggle switch for the flasher because the plastic ears are broken on my stock flasher.
I'm not as knowledgeable as you are about electrical wiring so excuse my ignorance, but could I just separate the wires bringing power to the factory switch (30, 15) from the wires leading to the relay, turn signal lights, and indicator lights (49, 49a, 58, L, R) and use a two pole grounded switch like this one?
TIA for any advice you can offer.
Jeff
