If you have strong electrical knowledge, such as installing multiple amp, caps, and other electronics into vehicles then yes try it yourself. It is not that hard, however you are going to be splicing into wires close to airbag controls and have seen installers trigger them by accident. If you are unsure at all of your skill to identify and properly splice a wire then leave it to a professional. Now by professional installer I mean a shop with MECP (Mobile Electronics Certification Program) certified installers, that either solders and heat shrinks or uses high quality Butt connectors, and do not use T-Tap connectors.
