i have an 88 f150 with the 4.9 300 i6 efi. i was wanting to swap the motor out of my 91 bronco it has the 5.8 351. the problem that i see is my entire wiring harness will have to be changed from the headlights to the taillights. is their an easier way?? i want to keep the fuel injection.

 

Just the engine harness/ ECU.

 

yes but the wires on the driverside do not have the same hookups it all runs into the main harness

 

IMPORTANT! Dont forget to take the frame engine mounts out for the v8, there are none for a -6.

 

i have all of that stuff.... i just need to know what i can do about the wiring harness

 

What's the big deal? Change the whole harness.

 

does any one else have any ideas??

 

There is no other ideas. You have to change the harness. You should be able to just change the underhood harness.
