ok so i managed to get ahold of the correct VSS plug for my T56 and now i have no idea what the instructions mean that came with the SGI-5 B box the i bought and im looking for help. this is not the same as some of the old calibration boxes that have been used in the T56 converion this is a "B" series.

has 4 on/off switches
a "up" button and a "Down" button for fine adjusting the speedo and has a green and a red light

the outputs for the wires are PWR, GND, Sig in, out1, out2, out 3, out4, and out5. i have the wires in the correct location but i do not know how to go about callibrating this.

is there anyone that can help???

 

Hey I am kind of in the same boat as you are in I can get my box to give me a reading but no where close to what I need it to read. Here is how I did it power - just a normal power wire I used one that would switch on when I used the key
Ground - Just ground use a ground wire
sig in - I took the wire that was running to my trans I believe there are two a yellow wire and a purple wire one is a sigal wire the other is a ground take the signal wire on and cut it the side that is on the trans side goes in the sig in
Now here is where I am running into problems the other side of that wire goes into the outputs but I can only get out put 3 to work and it either reads to high or to low depending on dip swithch 3. As for your dips 1,2,4 all off and 3 either on or off depending on how your speedo reads. Thats about it
