I have the '08+ style tow mirrors on my '05 EX from 1AAuto. My ex is a pretty basic XLT model that had factory paddle mirrors with heat and power adjust only. The new mirrors came with an electrical adapter that mated them to my factory plug and everything worked perfectly. (power adjust, heat, turn signal, marker lights). My new mirrors are rock steady at speed with no shake or vibration. An excellent upgrade!
The guy to talk to is "1ATony", he is the main man at 1aauto.
