Where to get a good MAP signal?

Where is everyone getting their MAP signal from for the hose barb style 2 & 3 bar MAP sensors? Can I T that signal and use it for other things like my wastecgate or is that not a good idea? If youve got pics I wouldnt mind seeing them.

Is that a pretty typical place that people use? Just dont want any problems with vaccum hoses coming off, 2 of my friends had that happen and it pretty much destroyed their engines.

i think its typical. The vacuum nipples are barb fittings and then i also zip tie them as well

Thanks, I'll look in to doing it that way.

I've seen some people tap the back of the hole in the intake (I think 1/8npt) and run a vacuum line direct to the MAP.

I don't like that idea, too many crevices for the shavings to hide and then get sucked into the combustion chamber.

I'd also like some pictures if you have any available. Are you putting the T visible on the brake booster hose or are you doing it closer to the rear of the intake?

For a safe, FI tune, I like the tube to go to the MAP only, and be a thickwall tube, ziptied at both ends, and be as short as possible. I'd tap and do the seperate hose thing.
