What exactly are you asking????

I have 94 motor in 91 truck And need new harness and trying to figure out what harness would work

This is the motor serial number, which should match the body and the frame. This means nothing when looking for a wiring harness.

Keep the 91 harness and just transfer over all of the sensors to the 94 long block. Done.

The two other plugs in cab that connect to chassis and dash harness well the grey plug that goes in the chassis harness is different other then that I could splice other connector on harness but idk about that her is pic of plug

Your making this difficult on yourself. A 91 22RE block is the same as a 94 22RE block. So, just use the 94 block and all your 91 accessories and harness.

I have a 88 with a motor I had 22repreformance build. I have no idea what year 22RE block is in my truck. But it's not a problem because I used all my original accessories and everything works perfectly.

What accessories are you talking about?

snobdds

Everything...

Alt, starter, intake, exhaust...everything. Just use the long block.
