Pcm help!!!
I am installing a Viper 5901 Remote Start / Alarm System on my 2002 Blazer Xtreme with the 4.3L Engine...
I have everything hooked up perfectly except for the dang Tach Wire... Every single guide I'd looked at tells me it's a White Wire in the Red Plug of the PCM and it's Pin #20.... Located on the passenger side engine compartment near fender...
I have had ZERO ZERO ZERO luck trying to find this thing... If someone could please post a picture or draw a treasure map... I need to get ahold of this tach wire so i can test this system out... Thank you!

. keep in mind mines a 2000 regular 4dr blazer (not sure if the wiring is different in the pcm or not) mines says pin 39 for mine so if that diagram kyle is showing is from an 02 extreme they must be different.
