This is pretty much custom fit for the 2004-2005sti or wrx, or other years with similar dashboards.
I have this cord that I made for my accessport. What it does is replace the USB cord from the dongle to the AP.
This cord has a 3 way switch and relay, ect…, and with it you can have the accessport either:
1.) switch on/off with the car (up position)
2.) stay OFF continuously (middle position)
3.) stay ON continuously (down position)
It takes about a half hour to install, and everything is plug and play. For instance the switch blank next to the I/c Spray is included, and you don’t even have to put the switch into the blank, there is a connector behind the switch for easy install. Everything is soldered and shrink wrapped/electrical taped to as oem as possible.
Looking to get $60 obo.
