2003 Pontiac Bonneville SE Without Monsoon radio wiring

[Neroadmantium]

Hi, I just bought my Bonneville a few days ago and I’m looking to install a DualTech Touchscreen Radio in the car. I found few articles with the wiring diagrams, but I am having issues with getting power to the new radio and don’t know what to do. Any light on how to wire in the radio would be great. I’ve read some people bridging accessory to the cigarette port, but I wanna know if there is any other way we can do this before I figure out a plan to reattach the factory harness connector and just spend the $80+ on the pre-made harness that is pre-wired for it. I’m trying to do this for cheap because I’m trying to get a place with my partner and living in Michigan is not cheap.

You will have to tap into an additional ignition source to power the radio. The OEM radio powers up from a Class2 data signal.
