I utilized the navigation interface unit from av electronics, so if you are using a different interface, your wiring to the interface would be similar, but a different color wire. Here goes:

1) Connect red wire with fuse from navi interface to grn wire of switch
2) Remove red/blk jumper
3) Connect red/blk wire (the one connected to contact in switch) to 12V (+) power ACCESS.
4) Connect blu wire to ground
5) Connect and splice red/blk wire from #2 in switch to contact #3 of VSA switch
6) Connect and splice red wire from #2 in switch to contact #4 of VSA switch

NOTE: IF YOU ARE LOOKING AT THE MALE SIDE OF THE VSA SWITCH WITH THE LOCKING TAB ON TOP, IT IS CONTACT #3 AND #4 COUNTING FROM LEFT TO RIGHT. CONTACT #3 IS POSITIVE, CONTACT #4 IS NEGATIVE
