I am just about done hooking up my 2 stage Dynotune window/TPS switch. I am just wondering which wires to use on my PCM for the tach and TPS. I have found pinout diagrams for 99-2002 LS1s, but none for the 98, which I know is different. Does anyone know which pinouts I use for the tach and the TPS? Right now it appears it may be the#12 dk blue wire on the blue connector for the TPS and the #35 white wire for the tach which is also on the blue connector. Can anyone who is familiar with the 98 PCM verify that? Thanks.

On the '98:

Tach Wire:

Blue Connector on PCM, Pin 35 on PCM, White Wire


TPS Wire:

Pin 12 on PCM, Dark Blue Wire

Sounds like you have it right.

Is the wire coming off the pcm actually white or is that which to hook to the window switch, how can you tell which pin number each one is??

The pin # is stamped into the metal on the PCM. The wire coming from the PCM is actually white.
