Okay so when i installed the new speed sensor the other day I saw a connector or two hangin around doing nothing... My reverse lights dont work at all... checked the bulbs, the bulb housings and all the wiring i could without ripping everything to shreds... Im pretty sure its something to do with those connectors huh? They wont go into each other so im pretty sure theres some cutting/splicing in my future here... My question is can anyone provide pictures of their rb25 trans and the wiring harness plugged in, just so i can compare to mine and see?(and yes, ive searched, yes im a retard and no im not high.)

Yeah the speed sensor is hooked up and works 100% I have to crawl under and get a better look but honestly i think its the only thing hooked to anything down there...

So does your lower harness not have anything to plug the trans into? There should be two more connectors
