that new rockies is expensive. theres this for the car that use it. all that needs to happen is a 50 or 30hz square wave when the key is on to the fuel enable wire to the pcm

I tried to build that bypass myself on a breadboard, and got close to getting it right, but not close enough so I gave up.
I found out that VATS was fine, as I should have known due to no issues with the security light, my MAF tip broke free and blocked the thermistors from reading.. :o
Thanks for the link to that, is it plug and play in-between the BCM, or does it go in place of the BCM?

depends on the car, on yours if its like the bonnie, there is a tdm. theft deterant module that reads the resistor in the key and sends the 50 or 30hz signal(fuel enable) to the pcm. the little board needs to be put in place of the tdm and send the signal to the pcm when the key is on
