Fitting Bipes ACU
 

Hello there,

I have a 90" Mazda MX5 1.6L Engine

Been fitting my ACU today and i have worked out where five of the wires go, just now im stuck on the "CAS in" wire. Where does this go and how do i find it?

On the diagram the wire for CAS in comes from the Crank angle Sensor and it actually says in the book:

"A firth wire (CAS) is cut, and each end of the cut wire is connected to the ACU."

Wheres that wire?

Thanks for your help

theres a cas in and a cas out on the bipes. at the ecu, you cut the cas wire, it should go: cas wire from harness -> cas in on the acu -> cas out from acu -> cas wire going to ecu plug. i hope that helps. solder all connections!
