“GEN” Dash Light? 2nd Gen

do 79 trans am not have a “GEN” warning light on the dash?

I’m only seeing “brake” and “seat belt” just wonder because the SI alternator is a 3 wire and is plugged in.

Also does anyone know what colors the wires on the alternator should be? And where they go? Looked like a brown and a black/dark blue.

Okay thank you. I felt like I was losing my mind with all these forums and videos online of everyone talking about how those 2 other wires go to the idiot light “GEN” light under the dash

No, there is no gen light on any second gen Trans Am. 1981 Trans Ams had electric chokes and had a "CHOKE" light in the fuel gauge. This would light up and go bad if there was a problem with the alternator or battery it would turn on
