Ya just splice in to it. I just have the 5.3 ecu. You will have to add some wires if your going with the throttle by wire.

I am using the Schoenfeld LS conversion headers for the 88-98 in my 95 2wd and they fit and work great, but I understand there are issues on a 4wd.

The wiring pinouts for the swap. When comparing them to the lt1swap.com the pinouts for a 411 pcm they don't match. Plus don't you have to splice in wires got the ignition Control?
