Since there has been several post/issues with DRL (daytime running lights) and other lighting issues/questions, I wanted to put some info in a consolidated thread.
Please feel free to correct or add information.
To start, DRL
In a nut shell.....
.
The Control Block is connected to the Relay Control Module in the Under-Hood Fuse/Relay Box.
Power leaves the Fuse/Relay Box via GRN/WHITE wire. Notice the No.17 (40A) fuse.
Then power goes to the Under Dash Fuse Box through No.3 (10A) fuse.
It leaves this fuse box via BLU/RED wire and goes to the DRL RELAY.
So the way I see it, when you start the Ridge, ground is applied to pin 3 of the Relay via the control block.
Current through the induction coil activates the switch on pins 1/2 in the relay allowing voltage to pass to the lights and Gauge control unit (dash indicator)
Whats odd is the trouble shooting steps don't mention No 17 (40A) fuse in the Under hood fuse/relay that I recall.
