Help with MAFT basic

[3.0T91]

So I have a MAFT basic that I got from a friend of mine. One problem: Which wires go where? I know I'll need to tap power, switched, ground in the car and plug into the stock AFM connector so the trickery can begin. Can anyone shoot me some wiring diagrams so I can sort this out? Any help is appreciated.

All you need to know is here.. if you have any problems/questions post them up, I've been runing MAF-T in blowthrough for a while now, if you go this route just try to keep the MAF sensor away from radiant heat like the turbo/valve covers. The sensor will get heatsoaked. Its a great setup, I love mine.

Thanks very much. That page was just what the doctor ordered. However, your mentioning not placing the MAFT over the valve covers is exactly where I'm placing mine for now. (I got some pipes to hook this all up from the IC to the TB) So until I get my new pipes, I'll ride as is. Thanks again for your help!

I keep trying to read up on going to MAF but everytime I try to read these links all I get is gibberish. :aigo: What do I need to download to read these? Thanks

hmm popped right up for me, always has.

Turbo87, over the valve covers should be fine, but you may need to keep an eye on it.. watch out for heatsoak.

You must have some software installed that I don't. I have tried to read this doc from two different computers (and one of them is new) with no luck. I will try again on my home PC when I get there in a couple of days. Meanwhile if someone knows what I need please let me know Thanks

Do I feel stupid. It would have helped I put some effort into it and scrolled down. The first page appears as gibberish but then further on is readable text. Thanks for putting up w/the slow person.

Heat soak should not be an issue. My valve covers were basecoated in that dupli-color heat paint (500 degree) before I did the silver topcoat. I'll keep an eye on it anyway though.

Yes I'm bringing back an old thread, but, in searching, I could not find the answer I seek.

I have recently acquired a MAF-T basic set up. In the MAF-T install guide, it says :

Pink - Switched +12volt power source
Black - ground (E2). MAF connector, Pin #1, Brown wire with black dot.
Green - Airflow signal (KS). MAF connector, Pin#3, Pale green wire, brown dot ,black stripe
Brown - Air temp signal (THA). MAF connector, Pin#4, Pale green wire, brown dot

....but in the TSRM EWD, Pin#4 shows to be light blue w/ red (VC) and Pin#2 shows to be light green (THA)

Anyone else run into this? I have both the 87 EWD and the 89EWD, and the Pin-out on the AFM shows the same.

You're mixing up the pin positions for the AFM and ECU. The Pale Green wire for example IS pin 3 on the ECU in that pic, but pin 2 on the AFM.

Your best bet is looking up the ECU's pinout and not relying entirely on the wiring diagram... unfortunately, I've found a couple instances where one or the other was wrong.
