injector signal location - 3.1 MPFI LH0

[berry]

hello all

my car has a 3.1 MPFI GM engine (LH0) and I like to install my mpguino.
where do I find the injector signal?

I appreciate your help!

my car: chevrolet beretta GT 1992 3.1 MPFI V6 automatic

**EDIT: Which one should I take? C11? (see the picture)
and for the VSS: B9 or B10?
thanks!

You've marked it right on that picture. That red mark with a "?" that's a good point to get injector signal for MPGuino.

it works!!!

I took the injector signal from the ECM and the VSS from the cluster.
Still in the calibration process.

Thanks for your help!!

Congrats! You'll love it like I do

the calibrating process is nearly finished, but I have issues with the mpguino. sometimes the display freeze.
maybe I need put resistors/diodes between the signals of the computer/dash/powersupply?
I took the power from the cigarette lighter

thanks for your help
