Hooking up reverse lights now mileage and parking light doesn't show on cluster
I just bought a 98 rs with a jdm 5speed swap from auto and I'm trying to hook the reverse lights up because the previous owner was too lazy to do so, when I hooked them up they just stayed on so I undid them and now my gauge cluster doesn't show my mileage or the parking brake light. I don't know what could've happened when they were working fine before I tried hooking up the reverse lights.
So after digging around and looking through the wire harness, I seen he cut and spliced a bunch of wires (very poorly) to get the manual trans to work. So I'm just going to pick up another ecu and harnes out of a 98 manual forester that way everything should hook up with no issues. The sad part is the guy I bought the car from works at Cosworth in Indianapolis and he does the wiring, I know he works there because that's where I got the car from and he took me and my friend around the shop.
