I have a Yankee 730/6 Turn signal switch. It has 4 wires. A black, blue, green, and yellow wire. Can anyone tell me what wire goes where for this? Thank You.

 

there should ber preety common schematics on line somewhere

 

I have found plenty with the 7 wire, but none with the 4 wire, but thanks.

 

If it's like most of them (and you have 3 terminals on the flasher)
Left-Yellow
Right-Green
Black-Flasher L
Blue-Flasher P

The X post on the flasher goes to fused power.

Here's a link

OK Thank You.

 

And, I forgot my manners... Welcome to FTE!

 

I like to modify these so that the pilot lamp flashes when turning or in hazard mode but is out when no lights are flashing. It helps me to avoid being the butt of a Galagher joke.

I simply use two $0.05 diodes and fifteen minutes of bench work later, viola!
I need to post a how-to. Gotta convince my son to take pictures instead of play video games. :ROLLEYES:

 

I'd like to see that post on the mod with the diodes
