MAFT and NEO install on 89 7mgte

[83restomod]

i already have the MAFT gen 1 installed and im going to stack piggy backs with the addition to a APEXI NEO. i already know to install the NEO in between the GM sensor and the MAFT box (thanks Billy) now im just trying to figure out the pin outs to get this thing going.

im looking here for my ECU pin out

here for my APEXI diagrams

and here for my MAFT diagrams
http://www.fullthrottletech.com/showthread.php?t=1102

i figured out all except 3 wires for the Apexi.

1) green wire----throttle signal

which pin out on the ECU should this one go to or does it go to somewhere else one the MAFT? i think it goes on the ECU casue there is no throttle signal on the maft, only RPM signal which is taken.

2) yellow-----airflow and pressure signal OUTPUT

3)white------airflow and pressure signal INPUT


i still have the green (airflow or KS) wire on the MAFT but i dont know if its input or output, im thinking it put since its getting the first signal of air after the filter. and i also have the brown (air temp) wire on the maft. not sure if these 2 have to be hooked to the APEXI unit but i just want to make sure.

im in pull through with the maft (its between the filter and the turbo inlet) like the stock AFM.


thanks

Double check these. I haven't installed a NEO... but it seems obvious to me.


For installation between the MAFT and NEO:

1) Gets signal from VTA.
2) Supplies the signal to KS (disconnect the MAFT from KS).
3) The line which formerly ran to KS from the MAFT Runs here now.


I'm not entirely sure how the NEO will act without a temp signal. I presume it won't make any difference though. Worst case scenario you can just feed it a static 2.5v signal.

CRE is right...
neo gray wire to the VTA pin on the ECU
neo white wire (input) comes from the AFM, which you have routed through MAFT
neo yellow wire (output) would be the new signal neo/maft made, going TO the ECU

no air temp on the neo, and the green on the MAFT would be input, since it's coming from the AFM/MAFT.. so it'd go something like

Green wire from pull sensor to white from neo --- and then yellow wire from neo to ECU

it's late.. but that seems right to me..
