It appears from the info on the coleherse site and your schematic that you are using the 75602-04 switch that does not have the self parking connection. I bought switch 75600-04 which has the self park feature. Can this switch can be used and just ignore the self park lead? I believe this is true. I need a little help with a part number on the bosh relays that you are using. It appears that 86 and 85 are the coil of the relay and 30 to 87 are normally open contacts. I dont exactly follow the connection to 87a on the center relay - does this go to a normally closed contact?
