I could use some help with 402/tbi/4l80e... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hi,

I am installing TBI on my 402 and a 99+ 4l80E transmission. I am getting some help from a local EFI guy. He isn't perfectly familiar with everything needed to connect the 4l80E. We know the correct late model ECM and have it, He builds his own harnesses, and he said we need the VSSB/DRAC and the connector. I see them on EBAY, is there a specific one needed or just a truck one from say, 94?

thanks

Andy
