Learned a lesson today about ignition solenoids. Do a forum search before buying a part. I bought the Blue Sea ignition solenoid that everyone is bragging about. Went to the coach to install it. Couldn't find it but found two relays that clicked when the key was turned on. Then did a search for the location of the solenoid and found a post by Don saying the later coaches don't use the large solenoid, instead use 2 smaller relays. I will upgrade my boost solenoid instead of returning this one.
