Good morning all! I walked into a great deal on a low mileage 04 5.7 and A518 so I am swapping that into the 70 Cuda. I have done my due diligence and printed MANY pages from the tech archives here, thanks to all of you that submit! I do however have a couple of questions I'm hoping to get help with. First, having trouble finding a premade A518 center hump, if there even is one. Second, I ran across a harness made by a member for about $200 that plugs into our fuseblock and into the ECU, has all the relays etc. Is it really that simple and that is all that's needed to manage the electronics? I got the whole harness, sensors, ECU etc from the truck. Last but not least, are most people doing this swap using the truck drive by wire stock digital signal box? THanks all, cheers. I will add some pics and an update now and again as I go! Along with some more questions I'm sure!!!
