Before I get flamed, I did alot of searching and have got conflicting answers on a couple of issues. I pulled the 3.1L in my 92 Firebird, and installed a 388ci carbed motor. What I need to know is without the ECM, will my speedo work without a different VSS box. And if I hook up the oil pressure sender will my in tank fuel pump run without changing wiring. According to what I have read some people say yes, and others say no. Thanks in advance for your help
