Figured so, just wanted some reassurance.
I ordered one last October from EBay with the electrical connector. I picked up a few male connectors at the wreckers today. The elec connectors are used on some GM vehicles in the engine bay for various things. I'll install the filter minder tomorrow, but it will likely be some time before I wire it up. I should have figured out the wiring when I had the dash out.

Kevin,
How is the long term testing using the minder? Are you still on the same filter and what numbers are you seeing now? I'm seeing 11 on my minder but still using it.

I'm still running the cleaned filter, installed 9/13. It's sitting at 8, not going to do anything till it shows over 20, so a couple more years?

Interesting, so your filter has been in service since Sept 2013 and it now sits at 8? Evidently you ain't hitting the dirt roads enough, LOL!!!

It's good to see that you guys are getting some readings. I did a bit of reading on these filter minders recently, and it seems sometimes they don't move at all, yet the filters are very very dirty. It seems also the location of the installation could be critical as to avoid transient or incorrect pressure readings.

Hate that mud...

Maybe the answer was given earlier in this thread, but how does the electrical sensor part work? Is it an on-off switch or a variable resistance? Did you know there's a "clogged air filter" indicator lamp position built into the 80 cluster? It doesn't come from the factory populated with a bulb, but it's easy to add a bulb and wire into the circuit. I wired up mine to indicate my interior winch control is activated, but it could be used by you to indicate the air cleaner is clogged.
I haven't checked but I assume the electrical signal is simply on-off. I purchased this version with the idea of one day wiring it into the clogged filter lamp. There are some links in one of the earlier posts with details. It's a bit gimmicky, but what the hell.
Installed mine yesterday finally. I'll try to wire it up to the dash light this spring.

It came with a Metri-Pack connector?
No, I picked the connector up at the pick-n-pull. Checked it yesterday, and it has actually moved!
I thought I would post an update. The filter minder shows that the filter is clogged, so I removed it and inspected it. It looks less dirty than my previous filter, but I decided to clean it as per the instructions. I installed the old one, and will monitor what the filter minder shows.

These filter minders use flow restriction to pull the plunger down. Wouldn't you have to match the correct minder to the corresponding filter to match the flow restriction? Example:
filter minder from a 20 sq.in. filter would have a different resistance spring/plunger for a filter that has 75 sq.in.
Yes? No?
filter minder from a 20 sq.in. filter would have a different resistance spring/plunger for a filter that has 75 sq.in.
Yes? No?

That makes sense but I don't recall seeing those numbers on the packaging.

Intake restriction is intake restriction, other than type of motor, diesel, turbo, etc, the "ideal" is the same within motor type class. A poorly designed/small surface area filter/intake will be more restrictive, require service more often, a well designed system less often. So, no need for differing units.
Experience with them on 1FZ motors says: Lots of wheeling (80 days a year) in dry, dusty, desert conditions = filter service at ~30-40K miles. Likely; less wheeling in more humid, less dusty conditions 60-80K miles service interval. Don't have any data on supercharged rigs, Inkpot is too cheap to buy one, more like, just service the filter at ~30K miles.
My guess, the S/C doesn't make much difference?

After replacing my filter and resetting the filter minder last year it has moved again. I will take some pics tomorrow.

I got installed in both my diesel Cruisers .. and in both cases it shows my filter it's clogged if I go WOT .. gotta say none of both it's stock in terms of air flow demand since one was NA and now it's turbo and one that was factory turbo it's not boosting stock numbers.
