transmission sensors

[240xGuy]

i got an rb20 in my 90 s13. originally, it was an auto, and now its manual. i didn't use any of the sensors or wiring off the old ka motor/trans. i know how to get my reverse lights to work, and i believe that is the first sensor on the transmission goin back towards the driveshaft? what is the order of the rest? and does n e one kno how i can get my speedo and tac to work? all i need to know is the order of the sensors on the transmission and wire colors to hook s*** up. thanks

Look at your 240 FSM, the RB20 transmission is pretty much a carbon copy of the KA transmission

cant quite remember which sensor is which but, I know that last one is speed. You can check the other two with a multimeter. Which ever one gives continuity in neutral is the neutral switch and the same for reverse. Both neutral and reverse are switches so there is no polarity so to speak, just as long as both wires are hooked up. tach sensor comes from the ecu
