Problem with wiring diagrams
OK,, this is going to be the first of many questions. So please be patient with me.
I've read the faq, and I didn't see this mentioned before.
I have a MS1 version 2.2 and I have built exactly like the instructions (because I built it like 3 years ago). I have GM water temp and air temp sensors. My N/A streetport will be breathing thru a weber 50mm ITB with 4 480cc injectors. I built errors add on card and want to use it with my un-modified CAS, but when I look at my original wiring harness pins 7,8,9,10,11,15 are all grounds. When I look at renn's modified wiring diagram, I see that only pins 8,9,10,11,15 are grounds. How do you modify pin 7 & 24 to be an input for the CAS?
What is pin 25 for on the modified wiring diagram?
Where does pin 27,29,31 connect to? (LEDs with pull up resistors? or somewhere on errors add on card?)
I hope somebody can help me.
