You could actually say there are 3 harnesses. Interiorupper engine harness lower engine harness (conects to your transmission)
You send them both upper engine harness's (RB, and the KA)
they splice it together, eliminate what you don't need and send back a working harness.
Then you take the lower harness from the KA and connect up your transimission sensors to the RB transmission.
temp sensor, speedo, tack, and everything else works like it did before. Only problem is that the tack and speedo can't read correctly from the RB25 (I hear the speedo works fine if you swap out the sensors from the KA to the RB20, but I don't have one so I don't know)I have been using an APEXI rev speed meter, until I get a chance to figure something else out.
rbsileighty, I have looked at the speedo pinions, but I haven't quite figure out what I need yet. I would hate to buy the wrong thing. I have been thinking about trying a speedo from a 300ZX, if I can find one:)
