The bulb circuit test info I have is for a 1999, 5.7.

With the ignition off, remove connector C4(black)from the VCM, turn the ignition on leaving the engine off, using a fused jumper connected to ground probe the MIL control circuit(brown/white, position #5/circuit #419)at connector C4.

The MIL is supposed to illuminate when that circuit is grounded at the VCM connector C4.

It appears as though there may be 2 brown/white wires at connector C4, the MIL circuit is position #5, the CPP switch signal(trans?)circuit should be the other brown/white wire in position #22.

Good luck.
