Ecm wiring diagram
I am trying to find where the up shift light is wired to in the ECM in a 1990 M6 coupe. Because I cant find the FSM for digital download I was hoping to get some help here. The diagram for the cluster indicated the light is wired to the ECM and to reference page 8A-20-4. If anyone would be willing to share the page or link me to a digital download of the manual I would greatly appreciate it.

I have a 93 FSM, would this be called the 'one-to-four' indicator? If it is, it is connected to pin 6 in the brown ECM 'D' 22 way connector. That is circuit 776 and is a white wire. I hope this helps but it is from a 93 manual and for a vin 'J' engine.

Pin A12 Lt Grn/Blk/Tan-Blk wire.
Here's a link with the pinouts of the ECM connectors: http://www.chevythunder.com/fuel%20i...0ECM%20PINOUTS
