I need help with my wiring harness.

I'm a newb, but I need help bad...

I purchased a 1997 Cali 7.3 E40D 2WD Crew Cab a couple months ago that had a light engine fire (leaking fuel bowl). I've got it pieced together but my concern is the the pinouts on the harness. The number on the burnt harness is F7tb121581 -cg p260f. I got a harness from a guy that said it was off a 96 but didn't know if it was cali or not and it doesn't have a ID tag. I would like to get a pinout on my truck, as well as a federal and cali 96 to verify my wiring.

Does anyone have access to this or know where I can get this information?

I did some reading, and apparently my harness did come in some 96 models, so this could be one of them.

Or, if someone has an extra harness with the same number as mine that they'd be willing to part with let me know.

Tony,

Check your PMs and email. Before using the stuff I sent, you need to look at the PCM and see if it is a DPC-202 (1996 Cali's would use this) or a DPC-312 (1997 Cali's would use this). I'm assuming you have an automatic transmission here. If it is a DPC-312, for something like this the best bet is to purchase an Electrical and Vacuum Trouble Shooting Manual (EVTM) for a 1997. I recommend getting one anyway if you just plan to keep the truck! The 1996 Cali (DPC-202) wiring is the same as the Federal. Hope this helps. Cheers!

Does anyone know about the glow plug circuit. I know that folks are going from cali to federal and I guess the glow plug circuits aren't of concern, but what about doing the opposite? Am I going to get a CEL not having those. I don't even think they exist on this harness, perhaps I can add it?

You can't add the GPR monitoring circuit unless you are going to run (or already have) a DPC-312 97 Cali PCM. Is that what you are going to run, but trying to use an earlier harness? In that case you would have to re-pin the PCM connector and add the appropriate wires (and shunt) for the GPR Monitoring circuit. I've lost the bubble on what you are attempting here, but if I already had a Cali (splitshot) truck that was running a DPC-202 (MIF-series code), I'd probably be jumping for joy! Cheers!

I have a dpc-312 pcm, and am running a 96 harness.

Does anybody have pictures of this shunt or where I can purchase it?

Side question, the pcm says remanufactured on a factory ford logo, did ford update these to make them less venerable to failure? Truck actually caught fire and I am hoping the wires burning didn't fry my pcm :/.

Ok, so after research, it looks like the shunt splits the wires into a right and left bank, with a sensor wire on each side. Do these wires go straight to the pcm?

Took me a while, but I got this figured out. Going to add the circuits I need incorporating the fusible links that the factory had (took me a while as it was so burnt).

They do run straight to the PCM, although they go through connector C138 (42-pin connector on the driver's side of the engine bay that also has the injector wiring in it). Cheers!

Still working on this. I got the truck running, but the throttle will not work. Truck pulled up to the spot it caught fire at so I would find it coincidental that the power take off switch went bad. I am chasing my tail on the transmission harness. I have the pinouts for the 1997, but:

If somone can get me the pinouts for all the plugs on the E40d trans off a 1996, or even 1997 for that matter (just to verify my data). I would be very grateful.

Is this something that alldatadiy would have on it (I need the location of each pin and what it runs on both years)

Thanks so much, this is really holding things up for me. I have verified function of pcm and it works fine.
