ok, i am running a rb26 harness on my rb25, and there are many differances, the biggest obstacle in front of me is the knock sensor harness and sensor them selves, on the rb25 the harness is intergrated into the lower harness, and they are green, on the rb26 they are black with a bolt through them and on a seperate harness that plugs into the upper harness, my first question can i splice my old sensors into the rb26 harness, or should i run the rb26 sensors, on top of that, does any other motor cross refence to the knock sensor harness since i do not have a rb26 harness perhaps a sr or ca ? any advice or input is apprecited, also i am running a power fc, so i know that i dont need the sensor (pfc does not retard timing like stock ecu) but i want it for the exta safety ( i have a wideband o2 as well as a egt sensor)

update

is it possible to splice the rb25 knock sensors with harness into the rb26 harness if i run the wiring to the ecu plug ?

last i looked the SR and RB26 knock sensors are identical. The harness plug to the sensor should be the same, however, how it mates to the engine harness would have to be checked.

if the two sensors read the same voltage i think it would work, if u just ran theknock senors directly to the ecu, using rb25 harness, going to rb26 ecu plug
