Exclamation Spark Plug change gone wrong

So I changed the spark plugs and the car is running smooth and fine with no hiccups or any other issues at all.
The problem is I somehow pulled a wire or 2 when taking the Intake Manifold off.
Anyone know how I can get these 2 wires back in here without taking the whole intake manifold off again or if I can insert them back in their places?

What is the cable connector called and can I order one online ?
Attached is the picture to show what I am talking about.

EDIT: I forgot to mention that since those 2 wires got pulled, I have all kinds of codes and the engine light on along with VSC.

Can u remove the connector and pull the wire out far enough to reattach the wire to the connector?
If not, you will need to remove whatever is necessary to get access to it.

The closest Lexus dealer is about 3 hours away one way.
I may just have to pull the Intake Manifold again and insert the wires back in their holes.

Agreed. Decouple connector and If the wires reach you may be in luck.

Most moisture proof connectors disassemble from the inside. As in, there are 3 shells. An inner lock, the part that holds the wires, and the outer shell that locks to sensor or solenoid....

Using two picks pry the inner section out. Then the next section comes out which detains the crimp contacts the wires were pulled from. Ideal is new crimp conntacts. More likely is you spread the crimp and reattach the wires crimping them again.

Less ideal is you solder them.
That said the shell, rubber moisture plugs must be slid onto the wire BEFORE the connector is reattached to the wire.

The question is, which wires go where??? Maybe the broken wire strands will guide you? Unless someone can provide wire colors/picture?
Good luck.

I ended up taking the grommets out, and sliding the wires back in, made sure they were connected and put electrical tape. I did have to take out the Intake Manifold again.
Thanks for your help!

Looks like someone has done exactly the same as you on the UK Lexus Owners Club Forum.

And done a more permanent fix using solder to ensure it not not fail.

What engine requires manifold removal to change plugs?

It's a little tougher than that, from the picture you posted it looks like you pulled the wires all the way from the base of the pin. You would have to take in the intake manifold off to fix it correctly as you'll have to disconnect the plug, take out the two pins and reattach the wires to them. You would be able to to this by carefully opening the pins and crimping the wire back on. I would also put a small amount of solder on it just to be safe. It's an easy fix but time consuming you'll have to pull the intake manifold as I said.

This or a wire repair kit from Toyota. Either way, solder.
