Has anyone installed an aftermarket remote start system like idatastart using an idatastart T-harness? Most of this is plug and play except for the connections to the 2 can bus circuits. They expect you to splice into the can bus circuit at the connectors on the firewall. This look impossible due to how little access there is. I am VERY hesitant about touching wiring on a brand new truck. The local aftermarket installer does this all the time for big money. Even if money was no object I would rather do it myself to avoid a hack job.
