Wtb-454/4l80 Ecm!!! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm swapping a TBI454/4L80 into my 92 Blazer. I'm in the process of repinning the connectors to run a 7060 ECM, but if you have a different one, that's fine too. REALLY close to getting started on this, want to do it all at once. If you have the harness to go with the ECM, that's even better!!! Lemme know what you got.

I might have one, let me see. Do you have a pict of what it'll look like? I have two Vortec 454's one was with the 4l80e, so I need to see if the ecm is with one of them?

If it's a Vortec, then I can't use it. I have TBI, years were only 91 to 93, maybe 94.

my 94 454 truck had a 7427 in it

Pretty much any of the early trucks that had that combo will work. I'll take what I can get, I can get the wiring to match the ECM. Was told to use the ECM you have, the 7427, but have the 7060 cause I know it was used in the 454SS trucks. I just want to get it going!!!!!
