Yes, it's the black box on the side of the tranny. I'm wondering if maybe it's different between the 5.3 setup and the 98 4.3?
I was sure I'd read on here where people knew what to do with it, but I can't find it now. Hopefully someone will stop in. I was told the fuel pump on the vortec trucks would be fine, and only the 94 down trucks needed a fuel pump. Man, it was easy up until now, and there are just a few things that are eluding me, lol. There is light at the end of the tunnel though, I've been impressed with how easy the swap was up to this point
