Direction rocker switch (F-N-R) for Zombieverter wiring?

[ScythianNite]

I hope this is the correct place to ask this information, but I am currently looking at control options for direction for zombieverter, and I see that there are options for both momentary switches and rocker switches. Additionally, I was wondering how ZV finds neutral, as I only see inputs for Forward and Reverse Direction on the pinouts.

I think Snowdog used a PRND from a Honda Odyssey.



Just the middle part pops out. Maybe that'd be useful to you?

If both forward and reverse selected, or neither are selected then in neutral. A rocker switch would need a centre position, that can either ground fwd and rev or leave open ( they are pulled down on the board ). A neutral push button would need a couple of diodes to either pull down or up both inputs.

Heh
Here you can see how i used one tractor direction lights indicator from a hardware store and i add two LEDs.
- In Neutral N means that neither of inputs is active and no LEDs are lit.
- For FWD one 12V input is active and one green LED is active.
- For REV the rear 12V input is active and amber LED is active.

There are several terminals on that selector which you could use for signaling direction to other devices, for example turning on the rear lights.
Or there was a push button option where you can press down on the knob to activate horn contact. This could be used as addition safety feature with direction change. Later on i will add stickers saying N, FWD and REV for MOT.
Other switch i use to turn on heater and the pump. I love the signal LED on the rim .

The cover is cut from 4mm transparent plexi plate where i sand the underside and spray paint it black. This makes the top gloss black and additionaly color cant be damaged on top.

thank you all! I do have a gear selector from a polestar 2, as well as its harness, but I'd need to figure out its CAN messages as well as its pinouts and I haven't had luck with that.

@mattsawesomestuff, I remember watching that video and I had considered that option early on, but wanted something to fill the gap of the removed shifter.

@Royhen99, that is the logic I needed to confirm, thank you for verifying.

@Arber333, That's exactly what I was trying to find, thank you for sharing!

I more or less have an Idea on how this works, so I will work on something for bench testing and resubmit on this thread.

Any progress on the Polestar 2 gear selector? Would love to have one of those in my future conversion.

hey, sorry I ended up picking up a bmw shifter super cheap but i do still have the shifter here with me. I want to get everything working on the build with a good understanding of why everything works before i start down the road of getting the polestar shifter working. especially since the polestar shifter buys me back all of the visibility at the head unit that i lose with the bmw shifter

I am using this style of switch
It has a signal and switch output. Blue led is not annoyingly bright.

What kind of polarity on the outputs?

tnx

What kind of polarity on the outputs?

There is a schematic/connection table is in last pic of my previous post

Drive outputs pin 2 & 7
Reverse outputs pin 3 & 6

pins 3 & 7 output +12v
Pins 2 & 6 output whatever you feed to pin 1.

LEDs are not controllable separately, they switch color depending on selector position.

My question was what kind of outputs are those? Are they open collector or positive outputs?
Are you saying if you supply GND to pin 1 then GND will appear on active pins?

tnx

Yes that's what I'm trying to say.
This looks to me like it is a mechanical rocker switch with rocker covered with a knob, so nothing fancy in that sense

There are two possible outputs for both D & R.
One is positive (connected to the +12v supply, which also powers the leds) and the other output is dependent on the pin 1 connection.
If pin 1 is not connected, you don't get an output from the pins defined as signal outputs.

I just got two of those direction switches and i am quite impressed with quality.
I put data on wiki where we can post also for other shift controlers. I will test them and review them more.
If anyone has wiring instruction for some OEM shift controler please post it here:
