Hey got a 88 crx used the factory engine harness off of it and I have a gray wire with two wires in it can anybody figure out what they are

 

Elaborate.

 

It did t idle right was looking around the engine bay and got a few wires not hooked up but also got a rywire set up from obd0 to obd1 got the vtec o2 sensor hooked up an the both sensors on the throttle body and still I'm throwing engine code 21 and 6 what does that mean I have reset computer three time and I can't erase it and that wir I was talking about it was the wire off of the original motor from the sohc to a dohc everything just about hooked up except certain wires
