Ok i'm doing a b16 swap into my cousins 89 crx si, now i know you need to ad 4 wires for vtec, 2nd o2, knock sensor and oil pressure.. Now a couple people i know said the ecm needs to see a vss signal for vetc to engage.. will the vss on the back of the cluster send the signal and are they pinned in the right location, also what do i do with the thing that sits under the speedo cable on the tranny and has the 2 hoses coming out of it... Thanks for any help

 

if you're staying obd-0, don't worry about it, i believe.

 

ok, i'll give it a shot....

 

with the B16 swap in EF's the VSS is in the Gauge Cluster on that one. Its pinned correctly already at the ECU for a PR3/PW0. The hoses you can leave open or loop between them. They was for powerer stearing which EF didn't come with

 

Thanks, That's what i was looking for
