Next is the fast idle control solenoid valve (F-I-C-S-V), which is mounted on the back of the Si intake plenum, near the EACV. it's plug uses 2 wires: black/yellow and a blue. Black/Yellow (later referred to as B/Y) is a 12V + and routes to the B/Y from the EACV plug. The Blue wire goes to pin B2 on the ECU. B2 is currently connected to the green/yellow wire from the "shift up light" in the guage cluster. The plug for this wire contains a green/orange and a yel/red wire. It is under the driver's side of the dash, connected alongside the fusebox with a white plug. Cut the green/yellow wire from the plug on the harness and splice in the blue wire from the Fast idle control solenoid valve, with the new wire going toward the ECU. Don't connect the F-I-C-S-V wire to the plug under the dash, or weird stuff will happen with your shift light! The "shift up" light is now disconnected (YAAAAAA!!!) and the green/yellow wire on the plug under the dash now hangs bare. F-I-C-S-V wiring is now complete.

crx hf to crx si...

this is not my post...i got it from somewhere another guy quoted it but there was no name of whom he quoted.

this is trying to wire the Fast idle Solenoid Valve on the back of the Si intake manifold...bumps
