Ok, so after a long day of junkyarding, I got a good speedometer cable, speedo sensor, and speedo/gauge cluster (incase the speedometer gauge was bad itself). Installed the cable, sensor and new cluster with the old speedo installed, and I now have an operational speedometer.

My question now is: I'm still getting code 15. The check engine light is not coming on while driving, but when I pull the codes, it's there. How can I clear the codes? I want to pull the battery cable but I'm pretty sure it'll trip code 12(?) which is "battery disconnected during last 50 key cycles".

Oh an what year grilles/core supports/fenders are interchangeable? I need a core support and drivers fender/inner fender. There are no good 1988's in the junkyards, only a 92, 85, and 91(I believe). I pulled a headlight bezel off the 85, but it is totally different.

Thanks in advance
