Wiring conversion HELP

[ra49686]

Ive got a 1991 5.0 from a grand marquis in a f150 frame with a 2004 4.0ranger cab mounted to that.What Im looking for is a wiring conversion .Yeah right a plug and play harness.Lights and accessories are good.What I need is the 4.0 engine plug to 5.0 engine harness.Are there any companies that make them.or has anyone done this.Thanks,this been going smooth so far,just not the wiring.

You will need the schematics for all three, does the computer harness for the 5.0 have the same tranny would be a concern along with the computer you want the computer/harness to match the type of tranny your running. Vehicle speed sensor and tranny type A/T or manual is there O/D. I`m sure something similar has been done a good VOM and lots of time.
