Bryan, did you get anywhere on your project? I ask because I am starting one very similar and was looking for pointers. I am trying to make a hill buggy out of an old dirt track car chassis and a 350 engine with a 1228747 ecm pulled from a 91 2500 truck. I got most of the wire harness for the engine to the ecm but not the part going from drivers side firewall to fusebox to column/gages. I need to figure out what exactly I need and what I can cut out.
I have looked at the schematics in the post Chewy pointed at but was wondering if a simpler diagram existed.
It would be wonderful to know what wires I DONT need so i could just remove them from the harness.
There's a simplified wiring diagram showing only the wires needed for a conversation. I can't find the original source, so I attached it to this post.
TBI only needs between 9 and 12 PSIG to work properly, certainly not "lots" in my book.
The man who says something is impossible, is usually interrupted by the man doing it.
Thanks for the quick replies and the diagram Grip. I'm assuming this will work with the 1228747 I have. It'll definitely help me figure stuff out.
Sorry for hijacking your thread Bryan but glad you got yours working - one way or the other.
