My lights circuit suggestion remains the same ( more detailed diagram )

As stated before you can run and splice the black traced wire to feed headlights into the SYSTEM POWER WIRE or fit an eyelet terminal on it and attach it to the Ammeter stud. You choose.

The original pink wire to lights switch is already around original fusebox of course. However check wich one, because there are couple more of pink wires around.



Also, you can splice the orange cluster ( dimmed source ) wires with the tan wire coming from dimmer lights switch. Both wires are really close to splice them together since the original fusebox already had those wires linked with an extra fuse, separated from both existant buss bars. You can also install a fuse holder in between too keep the original setup, just that the fuse will be floating on harness

a fuse holder like this:




once again is your choice

EXTRA NOTE ( not at diagram ):

the cigar lighter is originally spliced at the same point/fuse where the pink wire takes the power and feeds input to parking lights. Is not ilustrated, but the red wire for the cigar lighter can still keep spliced to the same wire/fuse than the pink wire to parking lights input ( so the same red traced black wire at new fusebox )
