ok now having brain fart. tried search and want to see how people have installed thier 3 bar maps?
do you leave stock one in?
and tie into another vacuum source?
thanks in advance.

 

and this is for use on an LS6 intake

 

Mechanically a 3-bar MAP is a direct replacement.

 

Courtesy of MM This is what he told me to do for installing my FAST 3 Bar MAP Sensor. Just run a small tube from this to the sensor

You can leave the stock map sensor in the hole and get reference from another port in the intake ...or just as posted above tap the hole for a fitting, looks to be 1/4 npt.

 

Is this a direct plug and play for an LS6? Sorry, don't know the difference between the back of an LS2 vice an LS6 which I have. I was under the impression that they are almost identical?

 

I have dozens of those on hand; they do NOT use the stock connector. The terminals aren't even the same. The factory uses Metri-pack 150 terminals and the MAP sensor uses standard Weatherpack terminals. Both the terminals and connector are different.

That 3-bar sensor uses this connector: http://www.lsxtune.com/shop/product_...roducts_id/464

The stock MAP sensor uses this connector:

I make a convo harness that plugs into the OE connector on the harness and will plug into this style of 2 and 3 bar MAP sensor.

Well it still can

It is plug and play on the LT engines. You will need the conversion harness on the LS engines.

 

ok great!!
one more question lol
are the pins in correct locations too?
just keep them in order? i have the plug for teh 3 bar. was just gonna cut the wires and put new plug on.
i have
grey
light green
black
the plug is labeled ABC
would i assume Grey=A light Green=B Black= C

thanks for the info!!

 

They are reversed from the 1 bar to 3 bar.
On the 3 bar, you should have,
A-Black
B-Green
C-Grey

 

thanks again been a big help

 

i got my 3bar from speed inc and they had an adaptor so no re-wiring 100 bucks for both

 

This is a good thread, I have a brand new FAST 3 bar MAP & harness from speed inc. setting on my desk but wasnt sure about what vaccume source to hook it to since it dosent plug into the intake like the stock one.

 

Some help..

that doesnt look like it works in the stock location...

 

Good to see there is another option out there as well. It is a couple of bucks cheaper than the Speed Inc harness adapter.
