For the guys that have used infinitybox's setup, what was the total cost of installing the system. Their 20-circuit harness is $1,500, but how much did you guys spend on additional wiring, connectors, sheathing, etc. to finish the harness? I'm debating whether it's actually going to be any cost savings over say iWire or similar. It does add more features but I think the cost part may be the decider for me.
