Tim240z Posted February 25, 2005 Share Posted February 25, 2005 I am going to put in a 5.7/4L60E Vortec from a 99 Suburban (63k miles on it) into my 71. Does anyone have a pinout diagram for the PCM? I have converted a 94 F-body LT1-T56 harness, so I should be able to manage this one too, but will need to find out what all the wires go to...... Can anyone help with that? Also, are there any editting tools for this PCM? I used TunerCat for the LT1, but this PCM doesn't appear to be supported by Tunercat, or LS1 Edit. Any Ideas? I think I will need to over-ride the VATS system to bypass the in-key chip recognition? Any help would be highly appreciated..... Thanks, Tim Quote Link to comment Share on other sites More sharing options...

I may need to hit you up for some more info.... Tim Quote Link to comment Share on other sites More sharing options...
