we are not on the same page for some reason, the wire colors i sent you should not change even though i am usa and not bahamas.

They were in the back of the headlight
Customer: replied 4 months ago.
Right here were the wires
Expert:  Lou P. master tech replied 4 months ago.

ok, can you 100% verify that the wires that are coming from the compressor and the valve block are indeed cut? seems unlikely based on the position of the accident.

Expert:  Lou P. master tech replied 4 months ago.

do you have the connectors on the other end of the cut wires? i can for sure help you but i feel we are not on the same page.

Expert:  Lou P. master tech replied 4 months ago.

if you can give me detailed wire colors with the stripe colors that are all bundled coming from the same harness that are taped up i can check the wiring diagram for the headlight as well .

Expert:  Lou P. master tech replied 4 months ago.
