Unfortunately it seems any documentation I could find is no longer active, ultimateyota.com seems to be gone. I have an opportunity to get a 2002 air box and MAF for next to nothing so wanted to know if anyone has the wiring chart on it. I think I need to re-pin the connector from what little I've been able to find.

It should open up the air intake considerably for the supercharger if you've ever seen the two side by side.

Luckily I saved pictures from when I did it!
First image (as long as I upload the attachments correctly haha) is the older style wiring and the other two are the newer style wiring

Just curious, but why? I don't see much of an advantage.

For me, my maf was on its way out, and I'd rather replace the cheaper, newer style maf than the expensive older style. I had an extra box and maf laying around so it cost me nothing to replace a failing maf haha

This is why:



Thanks for the photos! That is EXACTLY what I was looking for. So the first two pics show the old wiring order, and the last is the finished product? Looks stock too, so stupid CA smog techs won't think I've messed with the MAF or something.

Any tricks on getting the wiring out without damaging it?

$90 vs $800, I have a 98 and god forbid someday my MAF takes a dump I might have to give this a try. However, I believe certain year Camrys came with that type of MAF so there should be plenty around salvage yards.

How is this mod working out for you? Any issues?

I stupidly dropped my MAF during some engine work and broke it. I did this exact thing, got an MAF off a V6 Camry for $45. I was abhorred at the $700+ new prices I found from dealers.

Yeah, when I saw the price on Camelback's website I thought it was a typo.

Thanks for the photos! It worked perfectly. Just pry out the white lower part of the connector, release the little black tabs on the bottom of each pin and they push right out.

Started up strong on the first try. I'm really excited to see how the air flow is now on my supercharged 4Runner. The deckplate, combined with the Airraid intake and much, much smaller MAF sensor should allow a whole lot more air in than before.

It's been almost a week and I've noticed a few things with the swap:

The airflow is increased, which is obvious. However, I think how the sensor talks to the ECU is different. I put a 2002 MAF in a 98, and my Long-Term fuel trims appear to be through the roof, at idle or light throttle it's pegged at 19.5 (0 is normal). Mind you, I was already at 7-8 with the Airraid on there.

I expected to get a CEL any day for a system lean issue but it never came. 300 miles later and still no CEL light, or even a code to be seen of any kind. I think the ECU reads it right but my Bluetooth adapter can't make any sense of it. I'm currently 180 miles into another tank and I look to be gaining a little bit of extra mileage on this one, maybe around 19 MPG's or 300+ miles on this tank.

So if anyone does this don't let the readings throw you off. Let the ECU adjust and do it's thing and wait and see.

Cool you got it figured thanks to bambi_runner6. I have this bookmarked for later use...
96-98 MAF upgrade - TTORA Forum

also, at last check there is still a UY...

I did it 5 or 6 years ago and approx 65k. Still works fine.

This is definitely on my mod list. thank you

Just finished this mod and I have to say it was super easy and has a noticeable seat of the pants response. Thank you. much easier than finding a supra MAF and swapping it in. I ordered a cheap CAI for a 2001 ($69) and a new denso AFM for a 2001 ($59) about 45 min to install and boom started right up and runs really smooth.
