383 240z Posted April 16, 2004 Share Posted April 16, 2004 I've decided to build a 350 motor for my 73 240. I have a good 350 roller motor I can borrow (thanks Perry) just to get this thing done. I also have a TPI (85 version that has been changed to Speed Density) What I am in need of is a wiring diagram for a 90 Vette computer so I can build the harness. I have the diagram from ALLDATA and I removed the emissions controls, and left only the fuel pump and input sensors, ALDL, SES lamp and driven outputs (injectors, IAC, ect.) can it really be just that easy? I found that the part # for the ecm is the same as a 3.1L chevy so a quick trip to the junkyard scored me one of those. along with the connectoer I needed to convert my MAF harness to SD I know I COULD buy the correct harness from Painless but they got enough of my money already. I hope you guys can help me out with this. Either post here or e-mail me @ rx7260z@yahoo.com Keith Quote Link to comment Share on other sites More sharing options...
