I have a 2000 Excursion (49-state) that suffered a small fire. I have to replace all the underhood wiring.

My question is about the injector/COP harness- what year range will interchange, and are Excursions and Super Duties the same?

 

Ford's infinite wisdom has/had them making subtle changes to wiring harnesses between models and years so its best staying with the same year, model and engine you already have.

If you're experienced at following EVTM's and re-configuring wiring connector shells swapping different harnesses would be easy enough. If not staying with what you have is the best and quickest way to be running again.

Should be plenty of donor Excursions in the scrap yards---mind wire colors and their relative positions in the connector ends from the engine back to the PCM.

Thanks for the reply.

I have all the underhood wiring pulled out and laid on the ground in the position they were in when they were on the vehicle. I decided to start with the injector/COP harness, because it'll be the easiest to do. All I have for physical comparison is my 99 Super Duty 5.4- It looks like it has all the same connectors besides the injectors/COPS (all the sensors, etc), but without 2 of the injectors/COPS, of course.

So, pretty much, as long as I find a harness with all the right leads for sensors and whatnot, I should be okay with just maybe having to re-pin some connectors, right? I'm not having much luck finding any underhood wiring for strictly a 2000 Excursion.

One more quick question- when I go on car-part dot com, there are a few places that list having a "headlamp harness." Now, I've gotten pretty familiar with the underhood wiring on this thing, comparing schematics and tracing burned wires- there IS NO stand-alone "headlamp harness"- not on the Excursion nor on my truck. There is what I call the "main harness" that plugs into the three 40-pin firewall connectors and the PCM connector- that happens to have all the front lighting connectors, but also has the connections for the injector harness, ABS, the power distribution, and nearly everything else under the hood. Are they calling this the headlamp harness, or am I missing something?

 

Bro you are crazy....

I wouldn't take on that project for any amount of money.

Just scrap it and buy a good truck.

 

Why would I scrap a full-leather, fully optioned Limited for a minor engine compartment fire? All I need to do is replace some wiring, the master cylinder and a few bolt-on plastic parts. Easier than a transmission replacement. I just need to know what interchanges or what can be used with minor modification.

 

From my past experience Ford's running and/or model changes regarding pin out wiring can be quite the ****, a simple visual inspection almost never really working well. For this reason alone I do and always recommend the factory EVTM to direct or confirm all connections are correct.

Physically or mechanically its not difficult reconfiguring most factory connectors so if nothing specific is available this might be your quickest route to having your ride back on the road. I would suggest getting a used replacement harness as close to your year as that might be as close as you'll get without the exact replacement.

If just the wiring or other bolt-on parts were the only things affected I can't see scraping the whole Ex for a little fire. The known history alone is worth the time and money it'll take getting this one back on the road.
