97 Mazda b4000 with ranger bed. Original had a 3 bulb setup this bed had a two bulb and is guessing not plug n go. Question is can I use a ranger 3 bulb harness instead or find a Mazda original?

 

Welcome to the forum!
When you say 3-bulb, are you talking about the Cab/Map light? Tail Lights?
Does what you're looking at show previous signs of work (splices, broken harnesses)?
Don't take my word as gospel, but since they're basically the same truck, I don't see why you couldn't just use the ranger harness. Double check rockauto and see if you can't find a b4000 one there

 

Thank you!
I am talking about the tail lights. I was the one that swapped the bed and unfortunately must have tossed the original rear harness. But I think your right the ranger three bulb harness should swap, dosent directly say but I’ve read some signs that it should.
thank you for the reply
