The pins are accurate for the wire colors. The W/R wire that is suppose to go to pin(a) is the same wire that is suppose to be on pin 1 of the MAF. They all match up. I had an issue with my MAF as well. but the pinouts were different my wire that on a 97 was suppose to go to pin1 on the MAF actually was like pin2 of the MAF that I had. But then again, I don't think he was 100% sure on what year the MAF was from. I gave him my part number for reference so he could check it.

You guys have ohmed the wires with a meter to make sure that they are all good from one end to the other right?
Hopefully that is it. A pain but not a bad fix altogether.

hey, I just posted this in the main forum, but you know anybody who has the 96 EWD for the 4runner? I just need the 5vzeng.pdf or whatever they called it that year. This is to confirm that the pinouts aren't different... Looking at mosk's wiring stuff, it looks like the wire I spoke about above which is BR-Y in the 95.5 ewd, but his is BR-B. well the 96 is BR-B for that pin according to mosk's translation. So perhaps this is the same issue as what I had, and the plug for the MAF, which I think is already correct, may not be? Ugh... I know its right though. I just don't get it.

Scratch that you have the 96 taco harness. SO that explains what year that is for. pinouts look to be the same though. I say you need to test the MAF to see if you got a bad one or not. If you are able to look at the MAF call me. If not let me know when you can..

WOHOOOOOO!!!!!! purrs like a kitten! just needed to give mafm power and BAM! it runs great, and it sounds pretty good with no exhaust. has n e one done a cutout on the exhaust for these engines?

ahaha a cutout. its a y that is put into the exhaust before the muffler and cat. it allows you to be loud when you want, and be quite when you want. i have a buddy who had one on his ws6 trans-am. the car was semi quiet, kinda, until he opened the cutout and bypassed all of the actual exhaust.
i was just thinking about it because the 3.4 actually sounded good without an exhaust. i probably wouldnt open it often, it would just be something funny for all those glasspack chevy's rolling around town.

See dntsdad, all the wire colors were correct. But I may have not seen that on this year, the W-R wire from the efi relay needed to go to the +B on the ECU AND out to like 4 other things including the MAF. 
And Doesn't like magnaflow have something like that? Its a muffler, that has a butterfly built into the outlet pipe. You punch it, and the butterfly opens, and its like a strait pipe. You are barely doing anything, and its closed keeping it quiet.
I can't find a link online. Its in like all of the 4-wheel adventures magazines as an ad...

oh and i got up at 7:30 this morning to go to pull a part before work. i finally got an obd2 plug out of a 98 accord and a lower water neck from another 3.0 because mine was cracked somehow

with a quick call to hamish this afternoon to make sure the odb2 was correct, i finally scanned her. it had # cylinder misfire codes, which i think could have been due to the plug wires being wrong the first few times i tried to start it, and also not having os sensors or an exhaust yet.
i blead the radiator as best i could, so far only took 2gallons of 50/50 which seems kind of low, and back the truck up about 20 feet! hahaha she backed up real nice
the reason for not having a bunch of pictures and not driving it around is because i also changed the front diff on my buddy's truck, he broke the crap out of everything so we threw mine in it. i plan on throwing the hood on tomorrow, probably wiring the fan up to accessory for now, until i get a good reliable thermostat and then bringing it to the muffler shop!
oh and i am ordering some 5" 63" chevy springs tomorrow so i can eliminate the 6" make shift blocks i have right now!
