Can anyone tell me where/what these 2 connectors are for??
Hey everyone!!! I'm new on this forum, and need some help!!
My car is an 87 TA, with a 350 fuel injected.. Almost all the wires are connected, just can't figure out these 2. If anyone can tell me what/where these go, I would greatly appreciate it!!!

Guess: Air injection diverter valve. My '84 ccCarbed 305 has two connectors in that area and the one in the top picture at least looks familiar.

If the two are in the same bundle then its safe to bet them as the diverter valve controls for the AIR system
They are the right colors and both 2 pin

You don't have the "smog pump" on your engine and no diverter valve so these two will be left disconnected.
