There is a three wire connector at the back of the cab, behind the seat on the drivers side.
1. One Green/Yellow Stripe wire for Map Lights.
2. One Black/Pink Stripe wire for the Cargo Lamp, and interior light switch.
3. One Black/Blue stripe wire for the dome lamp and underdash courtesy lamps.
On trucks without the courtesy lamp group, from the three wire connector, there is only one wire going from the connector up to the dome lamp. Black/Blue stripe, and a bridge wire between the Black/Blue and Black/pink wires. The Green/yellow stripe wire isn't used.
Make sure you have power at the connector on the Black/Blue wire and it's not corroded. This wire connector is prone to get wet if the cab corners leak.
