Anyone know what the difference is between these two part numbers? I need to get a new one. Horn/CC don't work and Ive check every connection and fuse.

Which part?

Maybe 2 different interior colors, like black or red?

 

Call them and they can match it up by VIN #

 

I compared an 02 to an 05 and the 02 used p/n 204700 while the 05 used p/n 1777798. Maybe early 04s used the AP1 srs module? I'd call with your VIN to be exact.

 

Actually if you look them up on a site that lists the actual Honda part numbers, you could anwser your own question.

77900-S2A-A01 REEL ASSY., CABLE
77900-S2A-A02 REEL ASSY., CABLE

It is an updated part. Order either one and you will get the -A02 part.

And the 06+ part number is 77900-S2A-A51
