3 bar map sensor instalation help
Ok I know I'm asking a lot of questions lately but I need help and search and google just aint cutting it. I keep finding all kinds of stuff about 2 bar map sensors but nothing about 3 bar.
The problem is I have a fast 3bar map sensor and for the life of me can't figure out how to connect it. Is there some kind of pig tail to connect the stock wireing harness to the map sensor? I have tryed calling fast 3 days in a row and sit on hold for like 2 hours at a time.
Also I have read that the best way to connect the map sensor is by tapping the manifold and putting in a barbed fitting with a piece of vacum line running to the map sensor. That would of worked great if the engine was still out of the car but it isn't and reaching the back of the manifold will be a PITA! Also I would have all those shavings from tapping my intake in my engine I know they're only plastic but... Still don't sound like a good thought.
My idea is put it in its stock location but to... (hate to sound so redneck on this) gorilla glue it in place lol I know the stock one works because it sees no pressure since its under vaccum all the time but what about this idea with close to 20psi. Will it just blow it right out? Anyone have and suggestions and or places to get the connector also
Thanks!!

You can get the harness from Frost on here or Speed Inc. I would not glue the sensor in, Take an hour and pull the intake and do it right. Just be very careful of the oil pressure sending unit back there, I have seen quite a few people break that off, dont rip and tear to get the intake out.

You should be able to get to the stock vacuum line and t in there possibly do that without having to pull off the intake. And yeah you need adapter harnes.I got mine longer so can move my 3 bar its by my computer now easy to get to. No real reason to have it on the back of the intake. The fast like I have suck for holding the map in under boost. So I tapped my fast out and ran big line to vacuum manifold and then run lines to various things.Fast is easy to drill and tap.

I'm running a FAST 3 bar sensor and the harness that speed inc sells. Its plug and play providing you upgraded your vcm for a 3 bar ve table. The only bad thing that I have to say is that the adapter harness I got was pinned wrong, for 2 weeks my car would crank up run for 1-2 seconds and die. I finally tried switching the 2 outside wires around and it cranked up and ran with no problem. My situation was probably just a one time freak mistake at the manufacturer though.
Also what is a 3 bar ve table is that something else I'm going to have to buy or will that be tuned in when I get it sd tuned?
