2008 F350 Cummins swap harness question
Hey gang. Not sure I'm posting in the right spot? Seemed to fit? Please relocate this if not.
So I am getting ready to install a 5.9 12v Cummins in my 08 f350. I bought the truck with no engine. It had a 6.4 powerstroke. I bought it with the sole intention of putting this Cummins and a 5 speed in it. All that said, putting it in the truck isn't a problem. My problem is that the engine harness must have gone with the original engine. For the most part, who cares really. But I do need a couple things that the original harness provides. I would like the gauges to work like they should so I don't have to set up separate gauges for oil pressure and engine temperature,etc. I don't need much from the harness. I think just oil pressure sender, engine temperature sender, map sensor which I think will run the boost gauge, and tech sensor. And if I don't get boost gauge I don't care. Honestly could live without the tach also if needed, just be nice if the dash functioned somewhat normal.
All that to ask if anyone knows a good source for a pcm harness connector for the engine harness? New swap harnesses are insane, some over $1000. That's nuts being it's hardly a harness with what little a 12v Cummins needs. Guys around my area are wanting $150-200+ for used harnesses but have to remove them myself. That may be the best option? But I am fully capable of making the harness myself. I'm having trouble finding the plug that goes into the pcm under the hood. I can find sensor plugs and the main harness connector cover, but haven't found the actual plug itself. Is there any other PCM that uses that same style plug? I can search salvage yards around here, we have puck your own parts places around. Just rare to see a 08-10 powerstroke truck there. I only need that plug and half a foot of the harness and I can make it from there.
Anyone have any ideas or should I just go remove and buy a guys harness for a couple hundred and cut out the junk I don't need?
Sorry for the long winded post, thanks for reading!
