That's just a cold start injector connector. It's not needed.

UPDATE:

I got the new wire for the MAF extension as well as the 4th new MAF and it started and held idle, however, would backfire and have an almost anti-lag sound popping when the RPM changed, as well as a 17.5 AFR. I changed out injectors with a known good set but the car wouldn't start after that. I took out the spark plugs and turned over the car AND WOW IS THERE A LOT OF FUEL SPRAYING OUT! I then tested both sets of injectors out of the manifold and they all four spray continuously at max flow. Did I freak the ECU out somehow? and why would the car idle fine but have hesitation and popping under load? anything would help, thanks.

Bump, I swung by last night, the car runs, but it seemed like the timing was off some. I asked him to pull the starter and verify the flywheel was oriented properly at TDC, it is in the correct position.

After that he pulled some plug wires and determined there was no spark to cylinders 2 & 3, Without diving in too far, what could be some potential issues causing a partial no spark?

Bad wires, cracked/dirty cap?

Follow up on this bit of mystery I have replaced the following: coil, wires, cap, and distributor. I also checked and cleaned all crucial wires that signal the coil to fire and they are good. I now have spark on all four plugs, but it is extremely weak and intermittent. This is strange to me seeing that the coil produces a large healthy spark when the car is cranked! Any ideas are helpful! Thanks!

Did not see a rotor on your list.

I would triple check that the dist was dropped in properly.

I have successfully replaced everything at this point, cap, rotor, wires, plugs, and coil, which he all been tested and found to be operational on a 91 lh 2.4 wagon. I have all timing marking up where it should, and still a very weak spark. I noticed the distributor sparking and grounding to the block a couple times when my friend cranked it over. Is there a sure fire way to set up the distributor aside from using the notch and being at TDC? Thanks

The weak spark is not related to distributor timing. Explain more about the distributor sparking.have you checked all of the ground connections,even the negative battery cable?

Also did you charge your battery???? If the batt is like 11 volts or so, weird things start happening.

The battery is fully charged and is good to go! Yeah, so when I crank the car I hear all the right little cracks and pops of spark, but I get weak spark from the plugs, and I even saw a large spark shoot from under the cap and ground itself. I'll clean and check all grounds after work! Thanks!
