Yep! By 'power in that circuit' I mean at the 203 connector. From there it must splice off to the SCB which is under the seat, and to the power mirrors in the foor connection and also up the post to the dome and map lights. The break must be after the power wire to the SBCM splits off. Or in the kickpanel area. The manual might show that?

 

And in trying to check my output to cargo light on the back of the headlight switch I discover that the connector shown in the downloaded service manual...........looks nothing like whats in my truck! Great!

 

First, see if there is 12 volts at the pink wire on C203-pin 5.


If there is not, the problem lies between C203-pin 5 and Joint Connector 5-pin 16.


If there is 12 volts on C203-pin 5, the problem is between there and SPLICE


310, which is where all the wires to the non-functioning devices tie together.


SPLICE 310 is near the left rear speaker.
