Sequential shift light.
 
I've been looking up how to build a sequential shift light with my car, off and no, for the past six months or so. I assumed it was going to be a pretty easy process with MS2 but, it doesn't seem so. I have a basic knowledge of electronics, but nothing on the level of circuit building with MOSFETs or anything. Anyway, another buddy linked this to me today. I think the price is pretty fair for the DIY kit, which is something ~90% of this board is probably comfortable in building. Do you all see any flaws with getting this to work with MS? Not looking to be spoon fed, just looking for pitfalls so I don't waste 100 bucks.

Just feed it "tach out" from the MS. Youll have to use a pullup on the output.

Is that already square wave 12v signal? Right now I have that going to my gauge since upgrading to a CoP setup a few months back. Thanks for the bracket, btw.

I was just trying to remember if you had done that. I don't see why splitting the tach out to both wouldn't work. And regarding the voltage, since ms pulls it to ground, itll be 0 to whatever voltage the pull up is tied to, which is 12 since its driving the tach.

I didn't do it initially with the CoP setup. I don't know why I didn't.

I think this is sequential setup is probably gonna be the way to go for my wants.
