I just installed an aftermarket radio into my 2000 pontiac sunfire. I stripped the original cables and spliced them to the radio harness. I followed the radio instructions and this page: xxxxxxxxxxxxxxxxxxxxxxxxxxx(I can't post urls apparently so i pasted below.) to connect them. I ran the red wire to the brown wire on the a/c harness. The only remaining wire is a blue with yellow stripe which is for the steering wheel buttons which I don't have.
I can turn the radio on fine and it works. I can also turn the car on fine as well. But when I turn the radio on the instrument cluster shuts off and "error" appears in the odometer. The car seems to work fine with the radio on except for that problem.
I did try an obd2 scan and it just froze when I had the radio on. As soon as I turned it off the live data resumed as before. Only errors are ones from before - 02 sensor and fan circuit.
I grounded the radio black cable to a bolt behind the radio bay. The other two black wires from the original cabling are what I assume to be grounds as well.
How do I get the instrument cluster to work with the radio on?
YES I KNOW I SHOULD HAVE JUST BOUGHT THE 15$ HARNESS -_- But here I am.
