Wiring harness question redux - The 1947 - Present Chevrolet & GMC Truck Message Board Network

The only difference in injector connectors is if one was flex fuel and one was not. Being that the truck engine is an '01, I would say they are not and a 4.8 van probably isn't either. You can easily tell if they're the same or not since the flex injectors have a bigger square plug where as the non flex have a smaller more rectangular plug.

If you're going to use the van PCM with the truck MAF, be sure to tell your tuner because there is a difference between the two, but can be made to work in the tune.
