im installing a meth injection kit that runs off of the 0-5v output from the mass air flow sensor. so the instructions say i need to wire the 0-5v hot wire and the 0-5v ground wires from the MAF sensor...anyone have a diagram or know the colors of which wires these are on the MAF harness?

so far im hearing that the yellow with red stripe wire should be the 0-5v hot and the ground is black with green stripe..can anyone confirm this?

Here you go.

awesome man thanks... so the black with green stripe is definitely the ground but which one is the 0-5 v hot that i need? what does the number 5 with the letter next to it represent? one says 5v the other says 5n and then 5k. does the 5v mean 5 volt?

Try the one that says "MAIN RELAY". lol

seriously? im a newb when it comes to certain electrical things... not sure why the maf have a main relay.. excuse my newbiness but after all thats what this forum is for

bump..i really need this answered i dont know if mm was just ****** with me or not..so im still looking for an answer

13bturbofc

lol... anyways... how come OD's meth system is wired to the yellow with red stripe and he says it works?...

Because that's the MAF output, not the power wire.

13bturbofc

for future reference can you tell me how that diagram tells me what the 0-5v output is, or doesn't it?...

secret8gent

well it would if you were looking at the 'whole' thing.

here's a relevant snippet just for you.

well i was just thinking.... the 0-5v is a hot wire correct? and we were calling it that cause we were comparing a ground to a wire with voltage

"hot" always means power.
"signal" means the output of said device.

13bturbofc

yeah he knew wat i ment too....and in my book hot can mean any wire with voltage but power always means power and signal always means signal.. i never said power wire.but i digress thread closed...

"Hot" ALWAYS means power.
It NEVER means signal.
Now, you can say the signal is hot, but you have to specify it as the signal first.

hot means voltage , it is used much more commonly to describe a power wire but it can mean any wire with voltage especially when your comparing it to a ground...Miriam Websters agrees..."Charged or energized with electricity: a hot wire"

So, you've got two wires to choose from.
One is carrying about a volt and the other is carrying 5 volts. Which is the "hot" wire?

You are arguing a moot point.
You thread failed because you asked the wrong question.
Everyone that attempted to answer you did so based on your improper use of the word "hot".
That should be all the evidence you need to see where you screwed up.

Oh, and I can play that game too.

Dictionary.com:
First, a signal is neither "conducting current" (it is a varied voltage at a fixed current) nor is it a "high voltage", even in relative terms in a 12 volt system.
Even at its maximum output, the MAF signal is less than the supply of 5 volts.
