Hey all,I'm trying to get the SSI4 simple sensor interface wired to the BA I6 harness to log RPM,TPS,MAP & LOAD or Duty Cycle (they are the same thing arnt they?)AFR aswell through the serial port link along with logger,my question has to do with the wiring of the sensors like TPS;
In example TPS wires are;

Grey=A44-TPS-1
Grey & Red=A22-Ground
Yellow & White=A16-TPS-2
Brown &White=A21-5v

so is it A21 as posative and A22 as negative to the SSI4 channel for TPS?
Sorry if my question is stupid but I'm an absolute Noob in this area

Thanks in advance for any help cheers Johnny.
