1989 Chevy 350 out- 1994 Chevy 454 in - got a question now

[1989k2500]

The single green wire is for the temp sender on the cylinder head.

I found it on the dash harness side, but I couldn’t find where it connects on the other harness. It was midway , think. Does it reach toward the cluster or towards the ECU, Sir?

So I found the single green wire. It is bundled with the radio harness. Where does it need to be plugged in?

Let me dig out a '89 wiring manual and see if I can give you an answer.

Evil, the wiring is from a 1994. We swapped it after the 454 swap

The 94 wiring diagram shows that as a Dk Green wire with a C201A connecter. It's a serial data output (circuit #835) going to the DLC connecter, position J.

Ok, I could not find a single wire in the '89 diagrams. Sorry it took so long to reply I had a busy week end.

Thank you for searching, but as I said before, all of the trucks wiring has been replaced with wires from the 1994. But the wiring issue is fixed
