Speedo + reverse Light help!

[93CoupeSX]

ok, my buddy has a 1989 240sx auto - manual conversion w/ HUD. we just put the sr20det in it and the engine is running great! problem is we have no speedo or reverse lights. we are using the JDM tranny harness. I paired up the yellow/black and yellow/blue (there are 2 wires that are yellow and blue) for the speedo. and the green/blue and green/white wires for the reverse lights.. nothing. maybe since this is the jdm harness its a lil different? Please help me out asap. thanks!

One of the yellow/blues is the oil pressure switch, make sure you're not on it by accident.

you need a 5sp ka speed sensor, reverse lights wont work without some more wiring
