I can see the colours on them but I don't know what they mean, this is what I did on the resistor for the oil gauge, did I do it right? I was told to short it

Can you list the colors in order - I can't really make out what they are for certain. It looks like red - green - brown - yellow - gold...
On the back of what my cluster should look like, the ohm values are also printed next to the resistor.

If you can also list the colors, it would be helpful. I can't make out the colors exactly...reds look like orange, browns look like black, etc.

The one I bypassed for my oil gauge and took a picture of on my new cluster is red black black gold brown, the one on my new one fir the battery light is green red red gold.
The resistor on the back of my old cluster fir the battery light is green red red gold, the resister built into the back of the battery light bulb is the same, green red red gold

The oil pressure resistor is a 20 Ohm, (this is a precision resistor)
red 2
black 0
black 0
gold X 0.1
brown 1% tolerance
The battery one is 510 Ohm, (regular resistor)
green 5
brown 1
brown X10
gold 5% tolerance
red 2
black 0
black 0
gold X 0.1
brown 1% tolerance

Ok, that Cluster is the same as my new one. I shorted out the oil resistor because my old one didn't have one. My question about the battery resistors is that my old one had a resistor In the same spot as on my new one but it also had one on the back of the bulb, the bulb is the far left one on the right side section of bulbs. My new one is like the one pictured above where the light bulb is just normal

Wow, that has to be one of the dumbest things I've seen a manufacture do. So they addressed customer concerns on oil pressure readings by giving them a gauge that lies. They might as well have addressed the low power concerns by rigging the speedometer to not drop below 55.
This is good info to have though, especially since Ford's 'fix' can be repaired. Do you know what years this applies to IFT? Is it 9th gen's? Or 8th and 9th? I'm assuming not 7th, never seen a battery light in an IDI before, but most of my IDI experience is with the 7th gens.

These trucks don't have an idiot light, what Ford did was turn the gauge into an idiot gauge, with a real sender and gauge, the gauge will move when rev'ed up and show higher oil pressure when cold vs warm. With the idiot gauge, when the oil pressure goes over whatever the set psi the switch is at (around 7-10 psi) the switch grounds the wire and the gauge will move into the normal range and never move. Now they had to put the resistor in for the switch so that the gauge wouldn't peg to the max. If you don't remove the resistor (or in this case short it out) and you use the actual sending unit, it will read very low.
This is where the resistor is on the cluster, you will also see two copper points beside the SIG word that is were it would be shorted with solder, now if you don't want to solder it, you can just short out the resistor with some wire wrapped around its legs.
Hope this helps

Well my 88 originally had the resistor for the battery light on the back but no resistor for oil, and the 89 I got my new cluster out of had a resistor on both, the oil and battery, both had 7.3s

On a side note of dumb things ford did, I think the one that tops it off for me is the fact that the odometer in the 9th gen cant go to 400,000, and then they design it to roll back to 300,000.... how did they get away with that?

Actually both exist if you just have an idiot light it will be a switch if you have a gauge it will be a sensor both appear the same but are different internally. I have found several instances where the sensor has been replaced with the switch and the gauge sort of worked but erratically.
The diagram shows a switch but the sender will be in the same place.
