Does anyone know the color codes of the wires?

Locate the key reader wires under the steering column. It'll be a special two wire plug. Extend those wires so you can put your experimenters board in your center console. Then hook up your two wires between the two pins of your trim pots swipers where you Read your resistance. Now you can change your lock cylinder to one without the little thingy in the key. So now you can get keys made anywhere. Now you have permanent bypass for the system. I have this knowledge from converting my 89 Camaro's system. Here's the Kool thing, whenever you park your car grab your experimenters board from console and put in your pocket and your car is now disable. It'll turn over but never start. Also after you set to proper resistance super glue the trim pot screw so it doesn't move. I've included the resistance key blank chart above and use the design resistance column. You see I had to use the chart and my multimeter and test every resistance until my car started. With the trim pot method you can have the exact resistance because using resisters can be tricky and **** you off. You never need to worry about losing the resister in your key because that's what happened to me. Hope this guide helps you. Please don't cut any of ignition wires and throw that vats bypass module away
