I remember there was a topic of write-up on here, cant find it. Anyone know what wires need to be repin or move over?? Appricate the help guys

What are you doing. Auto to manual swap?

Same concept applies

Google is amazing.

How-to for changing the pins with pics and a couple of drawings of the wire arrangement.
brn(blu on 99)/yel/blk/wht, white never changes position
You may already know- when you clean the newer style maf be aware the 2 tiny delicate wires are down in one of the holes, not easily visible like the early version.

I want to thank you for all your contributions and writes up you have shared over the years and your continued presence on this site. You have a wealth and knowledge and its awesome you've stuck around for so long! So many people have gone on to other rigs or don't have time for the forum anymore. so a big THANK you!!!

I want to......

Like button isn't working so thanks, I appreciate it.
So many write-ups have helped and inspired me throughout the years, I hope their authors feel as good as I do when it helps someone else out. Life would certainly have been a lot harder without their hard work and sharing.

Just swapping to a better flow maf!

Thank you guys! I chop the pics up abit to make it easyier for some of us. I dont owned or take any credit for these.

I drew those pics and that is my hand that you've chopped to bits. Didn't know you were going to do that to them.

Here is the 96's wiring configuration:

And the 99+'s wiring configuration:

And the newly repinned 96's connector:

Also, I am not a guy.

For the 96 non-supercharged engine fuel economy and power has not changed. The benefit here IMO is the $600+ price difference between the two.

I'm not thinking this would improve flow over the 96. Fuel economy and power has not changed. The benefit here IMO is the $600+ price difference between the two.

Hahaha I apologize! I just to just have everything side by side! OCD

I did a vid... pretty sure this is a dead horse.

the best way is to get the air box and intake from a 99+ everything bolts right up and easy squeezey re-pin. I have been running like this since I posted. no codes at all.

Thank you! By the way I have a new solution on keeping the stock 96-98 box, with a insert tube from another car to make it work! Hopefully once I can get everything together I'll do a quick write up. The main goal is to use the stock 96-98 box and save the guys a headache on chasing down a 99+ air box. All bolt on no change the whole air box required, just replace the old restricted flow maf.

cool good idea. for me it was only a $20 donation to the pick'en pull for everything so that was a no brainer.

Can you explain what this solution is, it's not completely clear. I'm about to plunk down $100 for the whole '99 airbox-to-intake assembly just to get the updated MAF for my '97, but if there's a way to do it while retaining my perfectly good airbox and ductwork, I'm all ears!

Yes sir, you dont have to spend that much. I'm also trying to retain all my 97 intake box. I found my part at the junkyard off a Volvo s60 for $12.00 waiting to order my Denso MAF sensor from rockauto. Here a link for the right up.

Nice, thank you! I'm still reading through that thread, but if you know offhand you can save me the effort - if I get the Volvo tube/MAF, can I use the Volvo MAF sensor it comes with, or does it need to be replaced with the Denso/4Runner MAF sensor?

For us supercharged folks, it does. I'm no rich kid so I don't have before and after dyno proof but I have to swap it out periodically to pass smog. There is a noticeable power drop and sluggish throttle response with the old turbine-style MAF. But this is for a supercharger, which draws a lot more air than a stock engine.

Glad that others have saved the photos to keep 'em going, I have one saved somewhere in my build thread too. It's a very easy swap, just visit a junkyard and snag the whole airbox.

How I remember the wiring is you just move the black wire. It's either in the first or 4th position, the rest just slide over.

I cant comfirm on the sensor, but I did check on the Volvo it's also a Denso. You can try and let me know, honestly I rather buy a new Maf sensor anyway.&#55357;&#56834;

I have to swap it out periodically to pass smog.

I don't think they would check that on the visual inspection? They are all OEM parts, so I'm surprised a smog guy would notice.

I did have a smog guy find a slightly cracked PCV hose recently, that was pretty good... (on my Outback, not the 4Runner).

Fair enough, I'm no rich kid either, no supercharger here. Even though no dyno proof I'll go with your experience- and change my tune.
