Hello to all and thanks for creating this forum and fixkick info!!! its been a ton of help on my Geo tracker 
Well my question is as follows:
I've owned a 91 yellow geo tracker since '05, kept it stock til last year when I went full on on modifying it with dual transfer cases (kicker3), 10" lift long arm suspension, 85 toyota axles and 33" mud tires after all that the little engine wasnt able to go at highway speeds (max 60 mph to the floor) so I decided a little radical mod and installed a K03 turbo on it, As I read it on different sites the stock ecu and fuel injection components werent up to the task so I had to buy and assemble a standalone ECU from Mega squirt (MS) and modified the engine intake manifold to be MPI instead of TBI (made a 2" adapter out of aluminum and machined ports on it to install 1 inj per cyl)
Ok, so now Im running the spark and fuel from the MS, the stock dash has the speedo, fuel gauge, charging lamp, high beam, 4wd and turn signals working also installed an AFR gauge, a mechanical oil pressure gauge, boost vacuum gauge and engine temp gauge, but the Tacho on the stock cluster is not working...
On the MS site it expalins 3 different ways to wire for the tacho signal: Does anyone can reccomend me wich way to try and wire the tacho?
here's a link to those instructions

Also I removed all the stock wiring regarding engine sensors, ECU, radio, etc that were not needed anymore to make the new wiring look easier...
its been quite a mess for the last 13 months but at least its coming along
Here's a pic of my Tracker
Thanks for your time and help!!
