Yep, you need a return line for the hicas.
Dude, I would make it a priority to make the hicas work. Just me but it is such a nice feature to have. I would love to have the HICAS system myself..and it can be done without breaking a leg or selling a kidney.
Seriously, I have been told more than once that a braket can be fabed to use HICAS with the SR. Never done it but damn, I would not give that feature up...at all.
As for the wiring, something is amiss for the cluster to not work...but the other interior items should have at least an indication of getting voltage. Find the return wires and hard wire them to a battery block if nothing else with fuses. A car stereo shop can help you there with a buss block and fuseable links. Just find the returns and see if you can get 12V running back there.
I know this is a half informed post...but just my 2 cents.
