Ok I am finally getting around to cleaning up the wiring and other loose ends and need to get the port hooked up so I can pull codes and tune with HP how many wires need hooking up and can someone help me out with pin #'s or such. I have a schematic of the c100 but have now clue which wires I need out of the computer.
Wow nobody has any help to offer? :ugh2:
What year is your truck?
My truck is an '97 donor 5.3 is a 2002 supposedly. Really surprised I am having this much trouble getting this info I wanted to know how hard it would be to hook up the towhaul option too if someone knows that one...
Here are the pins I found on the ECM that pertain to the check engine and programming.
58
DK GRN
1049
ECM/PCM/VCM Class 2 Serial Data
59
YEL
710
Class 2 Serial Data
14
ORN/BLK
1061
UART Serial Data [Secondary]
15
DRK BLU/WHT
774
UART Serial Data [Tertiary]
And here is what I have from the C100
B6 Check Engine Light
B7 Serial Data Class 2
If I had to guess I would say that Pin59-->B7 but I don't know which pin the dummy light should hook to. Am I right wrong some one point me some direction so I can get something done while I am waiting on my transmission...
# 58 Im pretty sure. Ill be hooking it up tomorrow .
and the check eng light
46
BRN/WHT
419
MIL Control
I should have had it done alteady, but the bulb was burnt out so I chased my tail for an hour or so.
