HELP!!! Holley EFI wiring solution

I have a 2013 Camaro 1SS and the dominator system from Holley EFI. My main dilemma is in retaining stock gauges. I do not have the gauge cluster located in the center console area under the radio so that is not a concern. I mostly just need the stock ECU for AC, the dash gauges, and maybe radiator fan control (although I believe the dominator can handle this).

Does anyone have a wiring solution or advice on the matter? I already know that the dominator will have to share the signal wire from the crank sensor with the stock ECU for the tachometer to work.

I put one in my car but I removed every wire that was stock from the car completely. Although you can over lay them to with with the stock ECU as well. Try getting on the Holley EFI pages on Facebook there are guys that can help you with this for sure
