The white wire on the MSD window switch goes to the PCM, has anybody here that owns a 98 Fbody hooked one of these up? What wire on the ECM do you connect it to? The guy at MSD said pin 10 white....but that is for 2001-2002 I believe...from the pinout for a 98 I think it is pin 35 (white, Engine Speed Output) on the blue module. Anybody please correct me if I'm wrong...

 

Check out this link. It helped me a lot.

I have done research and the only thing i need to do is connect the white wire to pin # 35 on the pcm (im clueless here) I know where the pcm is now what? I TTT'ed this post so that you guys know I did a bit of research

 

If thats what it says just look at the top pcm and hook it to the #35 white wire. I think the PCM has small numbers on it doesn't it? Theres another post floating with almost the same subject.

I know on my 01 it was very easy to do. I had already run a wire of my pcm for my harlan shift light. So I just tapped the same wire for the window switch.
good luck
