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. So i went thru with these directions and still have nothing. I paired up the yellow/black and yellow/blue (there are 2 wires that are yellow and blue). and the green/blue and green/white wires.. nothing. maybe since this is the jdm harness its a lil different? Please help me out asap. thanks!
