I want to do the alternating turn signal mod on my 1st gen 2000 tacoma. I understand the relay method and prefer that way so as to not get backfeed in the circuit. The only problem is from what I understand is the alternating relay method only works when the marker lights are on. Now I would like the alternating flasher to work regardless of marker lights being on or not. I also do not want to cut the turn signal housing and add bulbs or anything like that.
