7.3 in an 86 F-350 4×4

[Gone Postal]

Im putting together an 86 F-350 crew cab dually 4×4 that used to have a 6.9 before being removed in favor of a Cummins swap which was also removed. I'm putting in an 89 7.3/ZF5/1356pto. Can I use the 86 wiring harness? This is my first diesel truck.

Yes you can, but you will have to use the glowplugs from the 6.9 as the 7.3 will probably have zd9 bullet style glowplugs
