I have a 1989 Firebird that had a 2.8 V6 in it with VATS, my question is do I need to do anything with the pass key or anything else? The new engine will be using a 2001 computer and a stand alone harness. I will also be using the stock gauges with the c100 harness and tach and speed from the computer
Thanks Rich

 

if you go into the LS swap section this is discussed at length
i forget its been awhile but disconnect the main wiring behind the drivers kick panel
-use the search bar at the top of the page and youll find everything you need

 

You'll need to bypass the start enable relay, and possibly tune out VATS from the new ecm.

 

I Know about the the ECM I was not sure about the old system. I am going to try and find more info

 

I am not sure why I didn't find it with my past searches but I found a great write up by QWKTRIP

 

where?
post the link for future users

 

I printed it and now when I try and search I am unable to find it, the title is How To Bypass VATS by quicktrip April 8th 2018
