question: will any DX, LX, EX cable reel work in my '01 EX coupe? is the only difference the number of leads running through it?

info: i have a bad (no continuity) cable reel/clock spring in my '01 EX coupe. it carries wiring for the horn, SRS/airbag, steering mounted audio controls and cruise control.

reason: my primary concern and motivation for replacing it is to get the horn working again. never have i needed the horn more than when i don't have one that works... so i looked at getting a DX or LX reel since it's about 30% cheaper than the EX-which has the added cruise and audio buttons. knowing if this interchanges would allow a broader selection at the junk yard if i decide to go that route.
