Here are the wire colors to look for. I bought a round guage style dash that came with the connector with wires cut off. This is what I found. (I don't remember what the dash pod came out of.) The power side of the CEL is just a fused +12V. Then you just ground the other side to turn the light on. You can see in Doober's print that it says it is brown with a white stripe. I found a yellow wire in the location. The pin number of the connector should be accurate though.
Actual data from a Dash
Pin - Cir Num Wire Color Signal
10 - 489 Yellow (Pass thru) CEL (Ground to illuminate)
11 - Pink, Black stripe Power side of CEL
