Wiring info sources

Hello everyone! Long time lurker, first time poster. I've recently expanded my car AV shop into doing remote starters as well. For the past little while, I've been using this site as an invaluable resource, but there are still some gaps in the coverage of vehicles. As my business grows, I figured instead of constantly asking for info on here, it's time to start going to the source. So, I'd like to know what the professionals on here use as a source for their wiring info. I have a WireColor subscription, which is great for most applications, but definitely has gaps in coverage. Where are you guys finding the info that you post on here? Any suggestions would be greatly appreciated. Thanks!

Two good free sources are readyremote.com and bulldogsecurity.com. A lot of people subscribe to directechs (the same folks that provide readyremote.com) with much more info.My ex once told me I have a perfect face for radio.
