Last night I installed a remote start in my 97 sts for the coming winter and baby. Everything works but it cranks too long in the battery sensing mode. I tried to hook the tach wire on the negative side of one of the coils - the car failed to even crank.

I am looking for an appropriate tach connection to use. I notice that the PCM does have a wire labeled tach output which is fed to the ipc. I was inder the understanding that the ipc used the data bus to get the tach data. Anyway, should I tap this wire and if so, where is the easiest place to access it.

Much thanks.
