98 obs

[Jarrett Dixon]

I have a 98 OBS that I'm swapping a 5.3 into. I'm using the 2004 5.3 pcm and wire harness to run motor and trans 4l60e. I'm gonna keep my stock PCM also because it was said it was needed to run the gauges if not running the 411. What wire do I need to get them working

No need to run two PCMs. The 2004 PCM will run your engine , trans, and gauges just fine if the tune is set up properly and wired correctly.
