so heres what i did, connected the lights as shown in the diagram- mostly.
light one has a black ground and a white power wire. light 2 has the same. i connected the white wires from both lights to a splitter on a third wire. this third wire is spliced directly into the center pin (light green wire) behind my trailer harness (if i had used the switch, this wire would go to the switch along with another ground wire and the power wire from the battery). i know the lights are getting power because i have the under tailgate light bar which is also spliced into the light green wire- which still works. there shouldnt be a voltage drop (or at least not enough) since theyre in parallel.
i also tried splicing it at the tailight, but to no avail (i used the colored wire that went into the reverse light, i figured the black wires were grounds since they went into the red tailight as well). there is also a red wire with a built in fuse that i did not use- this could have also gone to the battery (but the diagram only shows this wire used when i have a two prong switch- this set has a three prong. the three prong requires a ground instead). it also doesnt help that the diagram shows a blue wire connecting the two lights together- there was no blue wire included, but a black one instead. i also had an extra red (which would have been the wire to the battery) and tried connecting the lights with that wire, but also did not work.
maybe if i splice each light directly into the light green wire? i also didnt hook up the ground on each light, could that not allow for the lights to come on? or is it the cheap connections they use? the connections are cylinders ends that you insert into an open cylinder that you pinch together and voila, connection (im actually thinking of avoiding these connections all together and splicing all the wires together).
this is the first time ive ever tried to wire something myself, and its not going very well.
any help would be greatly appreciated.
