#2072, "RE: 034 EIC....I need an EXACT resistor and map" In response to In response to 17
The MSD's tach output, the little spade connector near the blinky red LED is a damn strong signal. I had my Viper alarm, my 034EIC, and my wideband all hooked up to it at one point with no resistors and it worked fine, I doubt the stock ECU's white wire would ever let you do that. If you are going to use it's tach output for a signal then make sure you have your MSD all hooked up and running properly before you install the 034.
