Picked up a 03 lariatCC with a shortblock 6.0 that the dealer had stripped. Clean FX4 automatic with 100,000 miles, no heads, PCM , door switches , Ficm , intake ect. So decided to go the 7.3 route and picked up a 2001 F-250 Ext cab 4x4 XLT that had rolled. Motor and trans bolted right in now for the electrical. Has any one on here been able to get the 2003 cab electrical harness to work with the older 7.3 main harness ie connector plugs C217 and C218 '01 with C213 and C211 '03? Or should I put a O3 7.3 engine and dash harness and keep the mainbody harness on the 03. Really don't want to hack this up so any input would be greatly appreciated.
:dunno:As you can see the PO did a number on the 01 7.3 steering wheel harness. One reason I wouldn't feel too bad about getting a fresh one for a 03. Looks like he had a security system and or some kind of engine display as it has a EGT wire coming up the firewall that was cut.
You can use a 02 or 03 harness depending on the build date, the 03 7.3 harnesses can be hard to find with a computer but if you can find one then just swap it out
So I found a harness off a 03 7.3 lariat. Would it be the same under dash harness needed to plug into my 03 6.0 CC body harness? Best option's for picking up a CPU and IDM? I have them for the 01 7.3 if they could be reflashed to work with the 03 6.0 dash? 1FTSW31F63EA74056 wire harness vin of truck they said was a CC, here's a pic of the 01 CPU with trans command.
Have a recipient 2003 CC lariat Fx4 6.0 engine , main dash, and body harness. Also everything from a 2001 XLT ext.cab that the 7.3 came from. Want to keep the 03 cluster and floor wiring harness as well as the 03 steering wheel. I'm trying to find the right main and engine harness to get it to plug together clean and fire free. Hard to pin down the right part numbers. :dunno:
After looking into all the harness and how few were actually made for that year I've decided to just get the in-floor harness for a 01 crew cab lariat. 100 bucks and change for something I know the engine will run with. To costly not using the donor trucks dash and engine wiring with all computers and moduals. Hope to have it up and going this week. lease:
