Help with identification
I finally
picked up a megasuirt for my turbo build and i have searched all over the net trying to identify the mods that have been done to the board as i need to re attache some of the D37 wires to the ecu adapter because they were crappy solders and came apart.
Can anyone help me out to see how i wire up the fuel pump as i have read 2 different methods and i want to make sure i done fry anything at this point
Car 1990
1.6
Any help would be appreciated

I had the same problem a while ago, I had to go through the manual, printed out a diagram of the MS pcb, went through checked every single diode, resistor, capacitor, etc. that the manual said to install. Then I removed all the wires and what not so I knew what I had on the board. Then I installed the mods that I wanted. I wouldn't risk just plugging and playing with a non pnp megasquirt that was used on another car.

I would however get a wideband asap, also make sure you have a gm iat sensor!

I believe that's a very early MS Labs MS2 if I'm not mistaken, like circa 2008? Actually I think it was just a preassembled unit from DIY and someone did all the modding, but the second opto-isolator for the cam input, and the colored wires, and seq. fuel/spark mods on the cpu, suggests Reverant.
my advice is:Stop moving wires around.
the other device is a KnocksenseMS unit.
The green Spare 3 wire probably connected directly to the MS2 CPU, I believe he was sending the knock sensor signal to it. Did this come with a harness?

Maybe abeFM or Frank or Thirdgen. Something about it looks familiar.
