Need to reduce a 12v digital signal to 5v

[lugnuts]

I have a plug and play application that powers the secondary trigger with 12v in the harness.
I understand that the VEMS needs a max. of 5v signal or it will be damaged.
I'm just a dumb tuner, can someone show me how to reduce the 12v signal to 5v?
Thanks,Kevin

I'm not sure where you got the information that more than 5V would damage the VEMS, it will take a 12V signal as the input is protected by a Zener diode.
Have you measured the output of the Hall sensor?  We've not come across too many that put out a 12v, the VW ones tend to give about 4V

Thats great news. In my first few weeks of research, I had a bad habit of not saving link locations, I'll have to dig-up that 5v comment.
I did not in fact measure it yet. While reviewing my manual diagrams it is showing that the 4 cyl cars share the 5v supply with the TPS, but the VR6 cars share a supply with other 12v components. I will verify this but it seems to not be an issue anyway.

I will delete the original post if you would like to avoid spreading misinformation.

Thanks,

No need, I have a policy on non-deletion on here because removing stuff looks a bit iffy.
Plus its a datapoint that people who may have read the 5v remark can refer to now.
