cheapest way to get hemi 3g going?

Joe,
Another issue I'm seeing is gauges and throttle kick down.
Getting something to convert the dbw to cable is fine, but how about the kick down for transmission? I am thinking of going w a 6 speed, but if i go auto, i need a kick down.
but the bigger issue, Gauges.....how does that work?
Granted I am not using the stock 05 ram gauges, and I am not opposed to doing something with different gauges...just thinking "how do i get signal" to them.

I can understand all of this in "theory"...but as to getting down and soldering in resistors and know what pieces to put together...beyond me at this point....I really need to get off my butt and get that EE/CE degree already.
