Flight crew of a super MD80 overshot the localizer final after given vectors by ATC to the localizer but no instruction to intercept on arrival. Controller said that it was an intercept course and that they should have intercepted rather than fly through it.

Narrative:
We were given a heading by socal approach. We understood the heading to be vectors for the localizer, but received no instructions to intercept. When the localizer came alive, we started trying to get clearance to intercept. By the time we could get the controller's attention, we had overshot by 2 mi. His response was 'yes you were supposed to intercept, you're 2 mi south, turn right to intercept.' I suggest that the clearance to intercept be included in the initial vector whenever possible -- in case of subsequent frequency congestion.

Title: FLC OF A SUPER MD80 OVERSHOT THE LOC FINAL AFTER GIVEN VECTORS BY ATC TO THE LOC BUT NO INSTRUCTION TO INTERCEPT ON ARR. CTLR SAID THAT IT WAS AN INTERCEPT COURSE AND THAT THEY SHOULD HAVE INTERCEPTED RATHER THAN FLY THROUGH IT.
Narrative: WE WERE GIVEN A HDG BY SOCAL APCH. WE UNDERSTOOD THE HDG TO BE VECTORS FOR THE LOC, BUT RECEIVED NO INSTRUCTIONS TO INTERCEPT. WHEN THE LOC CAME ALIVE, WE STARTED TRYING TO GET CLRNC TO INTERCEPT. BY THE TIME WE COULD GET THE CTLR'S ATTN, WE HAD OVERSHOT BY 2 MI. HIS RESPONSE WAS 'YES YOU WERE SUPPOSED TO INTERCEPT, YOU'RE 2 MI S, TURN R TO INTERCEPT.' I SUGGEST THAT THE CLRNC TO INTERCEPT BE INCLUDED IN THE INITIAL VECTOR WHENEVER POSSIBLE -- IN CASE OF SUBSEQUENT FREQ CONGESTION.
