theres 2 plugs off the rb engine harness ones wider than the other and they look like dash plugs, i believe the tach is on the wide one which is yellow and red, and goes to the yellow and red one on the ka dash plug, then the orange one goes to pin 43 for the start circuit, theres a blue and black one on the skinnier plug that goes to the blue and black one on the ka plug for the temp gauge. just off the top of my head though, ill try and get pics one day
