THANK YOU!!!!!!!!!!!!!!! The wiring diagram I have for the 318ti shows pin 79 is not used so I never gave it another thought. I just checked the connector and there's a pin there. This was the exact info I was looking for, nay, scrambling to find. I may still have an issue with the 5v VSS output from the cluster to 83 but I will def work on feeding somehing to pin 79. Is it 12v with neg pulse also?
I suppose I need to buy/build a micro controller to convert the wheel sensor signal to into something .this is way out of my league to build, though. Any info you have on that would

You have given me new hope since the only way I could see an additional signal was through data feed that I just couldn't have made work. Damn 20 year old diagrams
