Will the transmission wiring harness from a 95 F-150 work on a 93 F-150?

 

no clue, sorry I could not help. Just bumping your thread so others can read.

 

Thanks. It would be much easier to plug in a harness than the pan on the transmission to change the solenoid pack.

 

No it will not. The plugs are different because of the change to the solenoid pack and the PCM Computer.
They moved the damper diodes from the solenoid pack in 1995 to the computer.
The damper diodes stop the ringing (waveform oscillations or chatter) of the solenoid coils.

Most 1995 F150 trucks do not have a E4OD anyway, they have a 4R70W transmission in them.

Ringing waveform oscillation:

 

Only the 302 got the 4R70W everything else had the E4OD

 

Thanks for the info though. Switching from a 5.9 to the 5.8 might need to change complete harness at same time since I have it from donor truck

 

You did not say what engine and most F150 had the 302.
