CA18DET conversion question

[turbozx]

ok im figuring out the wiring before i attempt the conversion, iv sorted it all out except the speed sensor input to the DET ECU, since the ET ECU does not have a speed sensor input is it just left unconnected, if so does this affect the DET ECU?

What does the DET ECU do with the speed sensor input?

Actually doing this conversion to a Bluebird turbo, but only know of one conversion thats been done so far, seems a more common conversion in the
s12, so hoping someone here can help.

Thanks

Do you mean the rpm guage?

no it the speed of the vehicle the speedo on an s13 is electrical and the ecu takes a signal of this
