You are jumping the wrong sensor. That is the engine coolant temperature sensor that only the engine computer uses to read the coolant temp.
The engine coolant temp switch should have a green and a black wire going to it. On my 95 4-cylinder accord, the plastic connector was green as well. It should be near the thermostat housing.

Each fan should get power from separate relays. It is a design where one fan if a relay fails. If you have access to the original fan wires on the harness side, turn the key to the II position, then short the coolant temperature sensor A. Check if you have power and ground to those wires.
So number 11 ?

btw the fan hot and fan negative wires at the fan should be which color?

I would think blue and black based on the diagram you found. My 94 shop manual for the 4-cylinder says blu/yel and black. What are the wire colors that were cut?
The codes are for the coolant temp sensor. You likely set the codes when you had the sensor unplugged and were shorting the connector. Just clear the codes and see if they return.
Back to your testing. What happened when you tested the relay socket that turned on the fans, but switched the test light to the + battery post.

The wires on the con fan (which are running both) are blu/yel and black. --- the ones on the rad fan (cut) are blu/black and black
and yes, the codes --- lol I had the plug still unplugged. will jumper, key on, test light to + Post and touch that relay plug..

ok, further testing.. I hooked up my torque pro, watched the temp reading.. it got to 183, fans never came on. I turned the fan control dial to 1, water temp started dropping, fans came on... So Im guessing faulty ect?
