The yellow wire ran to the EGT gauge. As you can see, the truck has a full EGR/DPF delete. It was obviously not professionally done. Everything he disconnected (EGR, DPF, o2) was just left uncapped/wrapped and loosely zip tied to the nearest solid object to collect moisture and draw suspicion.
I'm still torn. If these mods were done properly (or this one was just tidied up), am I an idiot for letting this thing go? I'd just assume start from scratch with my own truck. Not buy a questionable hot rod from someone else. btw- I found out that it had two previous owners. Each dumped the truck after about 30k of driving... oh well.
