C100 pinout

[Dekarson]

Hi.
Im putting a om606 in my 1989 k1500.
I'm struggling abit with the wiring
Is there anyone who have a pinout for the c100 and the other connector in the firewall. It would be really nice if there were a pinout that show the colour on the wires and what it's for.

I have spent a lot of hours searching for it.

Here's a snip from my 88 manual, it s/b pretty close to the same.

Go to page 14 (or 18/146) it shows C100 and some others, HTH,
