TPS different on 87 and 91

Just looking at my harness from my 91 fb and the donor motor from my old truck they look the same except for a different plug on the throttle position sensor. Is this right? They are both 305 TBI just a truck 87 and the car's harness is from a 91 parts car. They are all going into my 86 TA.
I do still have the old motor and it is complete.

Has any body done this swap before ?

The rest looks good just a few holes in the block that need to be tapped for the serpentine belt brackets.
