'99 & up Upgrades and Aftermarket - 7.3L EngineUpgrading or adding OEM or aftermarket equipment to your 1999-Up Super Duty or Excursion with 7.3L Power Stroke diesel engine. Please confine discussion of topics in this forum to those items that are specific to the 7.3L Power Stroke engine.
How is it installed?
I have found where some say to splice in the banded end with the LG/BK and the other end of the diode to the Gy/R. Wouldn't this show 4.7v all the time to the PCM?
I have also found where some say that you Splice the diode into the center wire of the MAP sensor plug (green w/ brown trace) with the banded end of the diode to the wire. Attach the other end of the diode to your wire and run it to ground
So, is it even one of these?
Why does AE only monitor the MAP in Hz?
I tried it with AE set as a 98, 99, 2K, 01, 02 and 03. They all read Hz and I need volts to do my testing.
I understand that 5V goes to the MAP and 1V should be sent back to the PCM as a reference voltage. But that is just knowing that the PCM voltage is 5V.
A friend and I are trying to prove or dis-prove this mod. I have searched every site out there and find very little other than arguments but no data and/or proof of anything. I am racking my brain on this one here.
Thanks in advance,
Yes, this is multi-site posted.

In other words does it actually keep the SES light from coming on without effecting performance?
Yes it will do that. Wasn't sure what you expected. Some of the comments I've seen sound like a performance increase is expected. It won't do that.
Connect the end with the band, or stripe if you prefer to call it that, to the center wire of the MAPand ground the other end. One of the map wires is a ground. You can either ground to it or attach your own wire to the other end and connect it to another ground. I think the easiest way is to make a zener pigtail and connect it the way Banks does. You can look at their instructions on their website.
