I've read that for the 2013 Regal push-to-start, the t-harness is needed. Is this true? I have a manual transmission.
If the t-harness is not used, which wires actually need to be hooked up? Only the solid black lines on the diagram? I would of course be tapping into the factory starter (since it's push to start anyways). It seems as though some of the solid black wires on the diagram are supposed to be run to an aftermarket starter system, and not interface at all with the EvoAll (such as the +12V coming from the vehicle's pin 1 in the blue connector), which makes it seem as though I won't even be using all the solid black wires on the diagram either.
I've also read that the diode indicated in the instructions is not neccessary. Is that accurate?
Finally, the instructions indicate that I need to cut a wire in the factory harness. Is this accurate? If so, is there any other solution that prevents the need to cut a wire? Warranty issues would prevent me from straight up cutting a wire in half.
Thanks for your help.
