This is for my 2006 TrailBlazer SS 2wd, can someone tell me which wire on the pcm is the for tach signal? I need this so I can tie it into my maximizer II.

I went under the hood, I'll see if I can find the information so I know which one it was. :)

I used the white wire going to the insturment cluster and that works. The only downside was getting the dash out to get to the wire. Also I had to put the MSD box for 4 cly mode to read correctly.
Thanks for the help guys.
