Wiring Diagram. If you don't have the switch with the engage light or don't care about it, you don't need that relay. If you want to use it, this does work:

Using the same stuff as larolco
cruise control #250-1223: http://www.brandondist.com/products/cruise1223.htm
switch #250-3592: http://www.brandondist.com/products/Univ_switches.htm




Dispswitch settings. These settings offer a mild surge on set, but otherwise its pretty smooth. I am happy with these settings and will not be changing them.



BTW, one thing to consider if installing the rostra is the power draw. When the motor is pulling the throttle cable, it is using additional power, so if you run anything beyond heated grips and the CC, get a voltmeter and don't let it dip into the 12s.

Considering it works and both clutch and brake disengagement while you are using it I would say it's probably wired correctly. But not all rostras are the exact same model and yours may be newer than the one in the wiring diagram or have updated software.

That being said you may have to ground the blue wire off the rostra unit that is now going to the brown/black wire. It has something to do with a car having a clutch disengagement which the rostra doesn't like. I found a nice write up on a tacoma about it. It shouldn't affect how it works at all except take the clutch disengagement out of the loop.

Here is the article have a look for yourself

Anyone know if the 2017+ Wee's have the same wiring colors?

Thanks.

One way to find out would be go to a oem Suzuki parts seller
(Like Babbits online) and compare wiring harness parts numbers.

But since they deleted the emergency flashers on the 17 I bet it is different.

Well, I can answer that question - the wiring is different even though there are colors that are the same.
