Thanks doug, I did find one anyway, but thanks for the effort.
I sent a message to the company "Grote", but no reply yet (24 hours so far)
Must be to big of a company to give time to the common person.
I just googled it and it came up "universal turn signal wiring" from a source called
Mine has all the wire colors the same and works fine with the diagram shown but I still have an extra white wire. Everything works fine without this white wire, so no big deal, but I may play with this "Grote" company and see how long it takes for them to get back to me and explain what the white is for.
I think I saw, in all my searching, a post describing that the extra wire may be a ground.
It would make sense as white is the ground in trailer wiring applications. But otherwise, I would not have guessed in a million years how the rest was wired, the colors have no ryme or reason, yellow is not left, green is not right etc.
Oh, by the way, I can not see pics or diagrams of threads, posts or replies when I am on this site at work (some corporate computer restriction thing!!!???) so I can't see what you sent until I get to my home computer. So, your info may be the same as what I found.
But thanks anyway!
