351 efi wire harness ware can I buy

Im doing a swap from a inline 6 to a 351 I.have the hole donor truck with all the stock parts I need. But I was planning on buying a new harness and after market computer becouse I want to be able to plug my labtop in for plug and play for when I start modifing the motor. Every thing I find is for a 5.0 nothing for 5.8 s any info for a site would be great. I have tried painless wireing but mostly all for 5.0
Thanks greg

get a 94-96 302 MAF harness/computer with same trans from a F150 in the junkyard. and swap the MAF on. and mod the engine... doing stuff with the computer is worthless without internal mods...

StruckBy, he's a guy over on NLOC.org that builds harnesses and custom harness kits. He's here out of Orlando and has pretty decent prices.

theres no difference in the wiring harness.. the MAF computer is different but a 5.0 ecu will work... if you keep it SD you'll have to get a 5.8 computer as the 5.0 will run to lean on a 5.8
 
Well I talked to my budys old man he owns a local junkyard and hes willing to take my donor truck in on trade and let me take a 96 with a 351 stilll a 5 speed but the 4x4 is the electric instead of manuel shift will that make any difference computer wise

Same harness . 302 and 351 . About only diffs r number of o2 sensors. Most 94 newer 302 where MAF where the 351 are hard to find here with MAF.

I use the 302 harness on the 351 installs I do . You will need a like equipped truck Same trans to use computer the electric 4x4 shift is separate . I remove electric xsfer case and went manual no issues
