    Map connector B - PCM red 64 & dash guage
    Map connector c - PCM blue 47
    Map connector A - PCM blue23

    (This wiring is for '01 f body 2088 FTP sensor for vac pump)

    Im gonna double check my wiring as i might have gotten mixed up over the last year as ive changed from p59 pcm to the 0411.

    ***edit*** wiring is correct as per gm wiring diagram for 00-02 f body FTP sensor...
    Ah, I see, I was not aware you were pumping crankcase vac...

    good job on innovating with parts to monitor it

    My brand new Moroso 3 vane vac pump took a dump. Had vane material all thru the hoses and pump. Now i know why the guage was not moving from .82 in/hg... lol! I have to figure out why the pump failed but in the meantime i ordered a rebuild kit. Mon i drop the truck off to get full exhaust done finally and then i can resume my tuning. Doesnt make sense to mess around .

    That's too bad it failed... I'm curious as to what caused it.

    Yeah Joecar same here! Im thinking that b4 i plumbed the pump in i had the plastic intake and exhaust plugs in to keep dirt out. But i noticed they pertruded into the pump. I remember cranking the engine over to check oil pressure in the past. So im thinking when i did that the vanes might have made contact with the plugs and damaged them. I cant think of how else it could have happened? I have a rebuild kit on the way so it should be back up in a day or so and when i get the truck back from exhaust shop ill be back getting her dialed in!!!
    Ill take some pics of inside the pump when i break it down.

    Joecar i keep getting a p0463 code. In my pics i posted i have them set to no report and mil off. I left the tank vac pressure codes as non emissions in hopes i can record the data from that but the fuel level signal i keep getting a code... Any idea how i can turn that off?

    Doing the Rafig as, per the tutorial, do i set up a Histo for each temp threshold and adjust each temp in b4307?

    Also still not sure about p0463 code??

    For P0463, try setting it to MIL on (and Not-Reported).
