Not to jack your thread but for all other owners who are looking to install a standalone remote start system and want it to seamlessly integrate with their current subaru security upgrade they should definitely check out DEI's Valet 561T.
The 561T has additional features such as dedicated parking light output, true ground status output, rear defogger output, neutral safety check for ebrake check, and more.
The 561T can be had for $70, a turbo timer harness is about $20 and some other crimps/tape/wire etc... Do a search for online vendors that carry the 561T.
If anyone is interested, I can post info this weekend on how to install the 561T.
