Narrative:
I was working final arrival radar. I descended aircraft X to satellite airport to minimum vectoring altitude. He was unable to see the airport. He requested to receive ILS approach at okc to be able to descend below overcast. I issued clearance for pilot to turn left heading 010 degrees and climb and maintain FL040, (4000 ft). Pilot read back heading 010 degrees and climb to 4000 ft. Pilot turned right and passed too close to a crj aircraft on approach. No evasive action necessary. Both pilot and controller busy. Pilot read back turn with all clrncs except the important one. I believe, in the future, I will repeat direction of the turn and ensure pilot copied and or acknowledged.

Title: OKC APCH CTLR FAILS TO ENSURE PLT COMPLIANCE TO TURN INSTRUCTION RESULTING IN THE PLT TURNING IN THE WRONG DIRECTION TOWARD TFC.
Narrative: I WAS WORKING FINAL ARR RADAR. I DSNDED ACFT X TO SATELLITE ARPT TO MINIMUM VECTORING ALT. HE WAS UNABLE TO SEE THE ARPT. HE REQUESTED TO RECEIVE ILS APCH AT OKC TO BE ABLE TO DSND BELOW OVCST. I ISSUED CLRNC FOR PLT TO TURN L HDG 010 DEGS AND CLB AND MAINTAIN FL040, (4000 FT). PLT READ BACK HDG 010 DEGS AND CLB TO 4000 FT. PLT TURNED R AND PASSED TOO CLOSE TO A CRJ ACFT ON APCH. NO EVASIVE ACTION NECESSARY. BOTH PLT AND CTLR BUSY. PLT READ BACK TURN WITH ALL CLRNCS EXCEPT THE IMPORTANT ONE. I BELIEVE, IN THE FUTURE, I WILL REPEAT DIRECTION OF THE TURN AND ENSURE PLT COPIED AND OR ACKNOWLEDGED.
