Well first I have a 90 CRX SI with a B16. I have this extra plug "C216" which is Black/Yel - Blu, Now on the helms diagram for the D16 it says it's the dashpot control solenoid while the helms for the B16 says it's a purge cut-off solenoid. So are they the same or is this a typo?

here are some pics to compair the wiring

D16 Dashpot Control Solenoid


B16 Sugre cut-Off Solenoid



Other threads say that this is the Dashpot but it's only vacuum based?


I'm way confused with this plug so please help me out, o yeah my engine idles fine and want to know if I should hook this plug up or not?

 

what harness are you running? i would say if you were running b16 harness all around then fo with the purge cut off for that harness. but my guess is your still using the d16 ecu harness in that case you would have to figure something out. i know nothing about d16 except that i gave mine away didn't thingk there was a market for it at the time.

 

yeah I'm using a the D16 90 CRX Si harness, it's the harness that came with my car I just don't undersatnd what this plug is for?

 

its prolly for a system the b16 doesn't use. the one thing you have to find out is do you need the purge cut off

 

well from what I know it's not used unless I want to get my car bar certified in cali or something. Me being in Utah that doesn't apply

 

Bump, I would really like to know what this is used for
