Wiring is actually likely more complicated than that on newer (post 2000?) bikes ; the turn signals may be handled by the TSM / TSSM (turn signals and security module all in one!) - http://www.harleyshoptalk.net/forums...howtopic=29500
. Things like security, tilt sensors and "module" can get annoyed pretty easily. See www.jpcycles.com/instructions/pdf/380-215.pdf
for a procedure to reset the TSM / TSSM. I'm not saying this is part of what you need to do but it does show that that module might need a reset if you change things and resetting it reads like a video game cheat (Off, on, off, on, off, on, left, left, right, right, right, left, hold left, ignition on).
There is a standard - http://www.gpo.gov/fdsys/pkg/CFR-199...sec571-123.xml
"Federal Motor Vehicle Safety Standard No. 123 standardizes
motorcycle controls to minimize the risk of crashes resulting from operator errors in the use of controls." If a manufacturer doesn't follow it they can apply for a "Decision of Inconsequential Noncompliance" http://www.gpo.gov/fdsys/pkg/FR-2003...l/03-22041.htm
All well and good, completely besides the point though, there is only input and output, if you can make them match you can use whatever you want to switch it. Which means an adequate number of poles, no more no less.
The mechanical means simply doesn't matter.
and you certainly can flip it "on" both ways at worst you have to add a relay, but that is far from difficult work. A double throw/double pole can be wired to act independantly or with a common (such as pressing it down) that actives both sides. Its simply a matter of wiring.
