sup guys,
searched on honda tech for ecu pinouts so i can hook up my crank position sensor to CX harness with my LS ecu. Got the pin outs and which wires are which from the ecu,but now how do i tell which wire is the sensor input and which wire is the sensor signal coming from the snesor clip.one wire is blue with a red strip and the other is a white with a red strip. i just need to know which wire is the signal,and which is the input.

Also,to actually get it hooked up,i found out the location of the signal and input wires for the ckp sensor coming from the ecu,so now when i find out the signal and input wires of the clip,i just splice both signals and both inputs together? correct?

and while im at it,does anyone know where a diagram would be to show me how to hook up a 4 wire 02 sensor on a one wire CX harnes?

or does anyone know atleast a diagram of all the sensors i can get,or any diagram that will help me

y dont you check the sticky newb. theres complete pinouts in there.

ECU thread

i said i already checked the thread here on H-T,and the thread doesnt tell you which wire is signal and which is input for the ckp sensor,nor is there a diagram for the 4 wire 02 sensor hookups on a CX (single wire 02 sensor) harness

God you are STUPID!!!!

for the 4 wire sensor just wire it up like this

WHT wire goes to D14 which is O2 Sensor Input (needs to be a shielded wire with ground)
BLK wire goes to A6 which is Heater Control
GRN wire goes to D22 which is Sensor Ground
BLK wire goes to B1 or A25 which is Sensor volta

LOOK at the first thread in the forum.

ok,hanks for the info on the 02 sensor,but you didnt answer my question about the crank position snesor


and what do you mean when you say one of the 02 snesor wires has to be shielded with a ground?
