methanol injection install

[StraightXrs]

first off: this is for a corolla xrs

Two questions:

-Does anyone know where I can find an ignition/acc wire in the engine bay? Would like to not go through the firewall to get one if possible. (Electric Fan wires?)

-For those that have water injection, I need to get to the maf sensor signal wire...looking at the ecu pinout I believe I need to tap into e3-30 or e3-29. Anyone know which one or if that is actually the ones I need. Thanks

Is it possible to get the maf signal from one of the wires on the maf itself?

Try running it through the MAF, or get it through a bundle. Find correct wiring diagram.

i have found the wiring diagram for the ecu but cant find one for the maf itself.

The kit your using isn't boost activated?

You should be able to identify the MAF wire from the Greddy installation instructions :shrugs:

The MAF has 5 pins... you can tab the middle pin for MAF signal. I'm running a stage 2 on MAF sensor as well but I had problem when I tab the signal from the stock MAF... it will coz the MAF reading to drop about 100-200mv.... what I did was I installed a secondary MAF sensor just for meth injection.... :)

ok thanks for the info, will try that tomorrow!
