When you install it, do you use the filter minder that came with it? Mine had a socket for electrical contacts. Not sure why. I heard that those that came with the AIS are too sensitive. Should I put my OEM stock one in the box or should I use the one that came with the AIS? TIA
The "electrical contacts" are from a switch to trigger an alert that your filter is clogged, and doesn't do anything else if you don't want to use that feature. Use the new one that came with the AIS, I did and have never seen any restriction indicated. Never heard your "too sensitive" report, but that is what I'd want anyway, to let me know about even the slightest restriction.
Where do you get the rest of this stuff to hook up to the electrical contacts?
I don't know. When I installed the AIS in my early 99, I assumed this feature was a direct plug in for newer year trucks. I was told that it's just a switch that closes if the restriction gauge moves in enough to indicate a new element is need. Just run a fused 12 v wire through this switch to a light in the cab. But I'm sure everyone on FTE looks under the hood so often that they have no need of such a warning light, just glance at the minder.
You can build you own they started putting a dash indicator on in 02 i believe. One end of the connector to ground the other to the negative lead of an LED and the Positive Lead of the LED to a fused power source.
There is a huge article on TDS were one of the engineers from Donaldson spoke about the filter minder. Compared to the OEM by the numbers it is more sensitive but if you use a stock minder on an AIS it is not going to "trip" when the restriction gets to the point donaldson designed the filter to be changed at.
