Hi all. As I was in the process of removing parts to access the fuel injectors, I noticed a plug just dangling. It appears to be the same type of plug used for the fuel injectors, but those are all fully intact. As I trace the plug wire, it looks to be joined or threaded with another plug. I’ve taken pictures of both the loose plug and the other plug with which it seems to be related. Any suggestions would be a huge help! Thanks!

Loose plug

The other plug threaded along with the loose plug.

Just basing it on color of the wires it's "throttle position sensor plug"

Thanks for the suggestion but the the TPS has the correct plug. I’m just completely baffled as to what this loose plug is supposed to go into.

If it's on the same "bus" as the plug on the purge valve (the one you have pictured), then it's the plug to the switchover valve (circled in my pic)

Thank you, that looks to be the same plug! Of course it’s all the way in the back of the engine… What does the switchover valve do exactly? Would this have an impact on the speed density tune I’m currently running? Thanks!
