Using the lower RB harness

[alldus78]

I'm in a dilemma because I don't have the lower KA harness and I cant seem to find one any where. Yes I have searched on here for info about it and most of what I find is about using the lower KA harness. Is there any good info out there so I can use the lower RB harness. I know I have the series 2 RB25DET and its going into a 90' 240sx.

You can easily use the RB lower harness. You will just have to find a KA lower harness for plugs to wire it up to your chassis harness. If I were to do another swap, I would use the RB lower harness.

ya but I dont have the lower KA harness

Then it might be kinda tough to find plugs that fit the female plugs on the S-chassis. You can either find the lower harness in a junkyard or buy new generic weatherproof plugs and replace the existing plugs.

I'm sure you can find the lower KA harness anywhere!

I've checked every junkyard and auto part recover center within 150 miles, I've checked advanced auto and autozone. the only place I haven't checked is the dealership but I fear that they r gonna rape me on the price

If you honestly can't find one, just buy some universal plugs and cut the female S-chassis plugs off and wire the new plugs up according to the "lower harness prep" guide. The plugs obviously don't matter, just get the wires to connect properly.
