kkreit01 will become famous soon enough

If you have to ask, you might want to take it to a shop. It will be a lengthy install. I installed my LC6i last night (same thing -- w/o bass restore). There are several different ways you can grab the signal from. You can grab all the high-level inputs to your LC7i at the output of the OE Alpine amp -- under the dash. I grabbed the front door speakers from there, grabbed the rear door speakers from behind the B-pillars (right before they go into the door), and grabbed the sub right at the sub. Make sure to open your LC7i, and change jumpers to SUM all signals. I ran power for the LCi straight off my amp -- with a 1A inline fuse. GND was same location as my amp. Then run RCAs from the MAIN output of your LCi, and Remote Out trigger from your LCi to your amp. I already had my amp installed, and most wires ran. It still took some time. If you plan to do all at once, and are inexperienced with this system, you better set a whole day aside. You'll need all wiring diagrams (color codes) for OE system.

In the end, the device works perfectly as designed. I now have a full-range signal to my front speakers. It's take some adjusting to get the EQing set right. Your FR-RR fader will also be a little goofy -- whatever is run off your amp will fade both Front and Rear -- since a mix of signals is feeding it.
