Traction Control reversal module for your 96 Z28
If you have traction control on your 96 Z28 and like me, you want to install a traction control reversal module, you were out of luck. Until now. I found a company that makes an "Auto OFF TCS module" that fits many late model GM products. Here's the link: http://www.easyperformance.com/index.html. Click on the Auto Off Traction Control System Module link. They only list them for (and have instructions for) 97 and up vehicles, but after contacting them and looking at my wiring diagram, I figured out how to make it work on my 96. Here are the steps below.
1. Remove the console. Refer to your service manual if you don't know how to do this.
2. Remove the connector from the back of the ASR switch.
3. Locate the Accessory plug wiring coming from the console wiring harness (it should be labelled). Find the end of the pink wire by peeling back or carefully slicing the tape around the harness. Crimp on a female spade connector.
4. Install 2 of the provided crimp-on T taps on the wires that go to the ASR switch. One on the black with white stripe wire and the other on the brown with white stripe.
5. Connect the pink wire of the module to the pink accessory power wire. Connect the black wire of the module to the black/white wire and the white wire of the module to the brown/white wire. Plug the harness back into the ASR switch.
6. Test the operation of the module by starting the car. The "ASR Off" light will be on initially, then go off once the system initializes. A few seconds later, the "ASR Off" light should go back on. The module waits 10 seconds after the car is started before cycling the ASR off.
6. Put everything back together. Enjoy not having to turn your ASR off every time you start your car! The switch still operates like normal. You can turn on the ASR whenever you want.
I bought mine from the only place that seems to carry them. It's called ZZ Performance in MI. The URL is http://www.zzperformance.com/. You have to buy the one for a 97-03 Pontiac Grand Prix because that's what they carry. It still works. The only difference is which instructions you get.

Waste of money and time. I bought a $1 resistor and plugged it into the connector going into the black box over the valve cover. Works like a charm 
. ASR switch operates same as before, only when I lose traction the gas pedal doesn't kick back at me. EBTCM doesn't throw any lights, works perfectly. The resistance value you need is 2.7 ohms.

Thanks Lee for taking the time to post these detailed instructions for the earlier model 4th gen ASR "Auto OFF" mod. This is something that has been asked about many times in the past.

The resistance value you need is 2.7 ohms.All I know is, I ALWAYS press the button before I start driving, so I wanted it to default off, but be able to turn it on if I want. ASR has only helped me twice. Once I was trying to park on a slippery grass hill at Sears Point and it actually helped me get the car parked without sliding sideways into the car next to me. The other time, I was on snow/ice. Since I live in California, I have no experience driving in snow, so it helped me get out of the parking lot I was in.
I would prefer not to have ASR at all, but I'm not interested in removing the whole system. I don't like working on cars that much anymore!
