hey guy i just bought a si shell and i am going to put a single cam from 97 civic no vtec. but i know i have to use a 99 hernes so i got a new 99 si hernes but i notice the crank sensor is different. what else is different that i need to work on. thanks for the inpts.

u dont need to worry about the crank sensor, it will not need it.
Is the shell a 92-95? if so u need the 92-95 harness...

young geezer

no the shell is 99 si and the motor is 97 civic singal cam

If the motor is a 97 Si then it is a Vtec motor. You're confusing me.

1st there are no si motors for 97.

and why would you but a sohc in a dohc. find a b16 and drop it in. d16 no go dont do it.

young geezer

yea i am puttin a 97 singal cam in my 99 si with the si harness. i am going to take it out soon. but till then i ll drive this way. need a running car fast. i just need to know if i splice the crank sensor from the 97 motor to 99 si pulg on it. and dont throw any engine light on.

Are you using the Y7 ECU too?

The 3rd wire on your D16 harness that doesn't match the B16's sensor is just shield ground for the CKF. Don't bother hacking your harness. Search for the CKF trick. It just uses the CKP output as it's own, since they're same 'shape'.

You've got to worry about the 3-wire IACV and adding a third wire back to the ECU though, since the B16 uses a 2-wire IACV.

You don't have to worry about a KS, since the Y7 ECU doesn't look for one.

You don't have to worry about VTEC pressure/solenoid, since the Y7 ECU doesn't look for those either.

But because you're using an OBD2a motor, the distributor plug is different than your 99 Si harness. OBD2a has the tach signal coming out of the distributor. OBD2b has the tach signal coming out of the ECU - that's where the 8 vs 9 pin difference is.

Is this a car you're trying to get to pass emissions?

yea i already cut the 3 wire from the crank sensor and use only 2 wires from there.( the white and blue). and splice in the si crank sensor which only has 2 wire(white and blue) now my question is will the engine light come on? and i need to pass the inspection so i cant have engine light on. thanks.

EE_Chris

The light won't come on assuming you've got things wired correctly. As I also said, you can do the CKF trick if all else fails.

young geezer

what is the cfk. i really need to pass this inspection. thanks for all the help.
