Do you have a pigtail for that 4th plug? If so, I can help you by telling you about wire colors and where they go.

Yes, we managed to get the pig tail.  We found a Grand Vit to steal wiring from.  Any help would be great. 

PM me your email address.  I think I've got all the wiring diagrams for an '02 XL-7 in .pdf form.

There's 18 of 'em.  That would entail work.

I emailed the .pdf files per Drone's PM.  Hope they help.
 
I'm pretty sure '03 had the redesigned dashboard (which is why I went with an '02 XL-7 donor into my '03 Tracker with its old-style dash, hoping to eliminate at least some measure of complication), but I imagine things will match up reasonably closely. 
 

And how did your conversion go?  Did you change ALL the wiring, or were you able to cross into your dash and body wiring?

I have not seen the email yet.  Did it bounce back to your server?

I swapped out every last wire in the truck.

Well, that sucks.  Nope, didn't bounce back.  I'll try to log back in to my work machine later this evening and try again.

Do I have to change out the fuel pump and gauge for one with pressure and temp sensors?  Or will it work without the sensors?

First, let me say again there are many ways and philosophies on how to integrate a engine swap's harness into a vehicle. I use all of the guage and hi power wiring from the original vehicle and 'splice' in the control wires from the new harness. So, what this means for the fuel pump and guage. I would leave the guage wiring undisturbed, it works fine as is. For the fuel pump, I use the original (car) relay and find the control wire coming from the ECM and splice that into the coil of the relay (low power side). On the xl7 ECM it should be the E61-23 and will be White with a Green stripe. To test put a continuity light on pointer on a know 12v source and then clip the ground clamp to this output from the ECM. Apply power and you should get 3 to 5 seconds of light and then it'll shut off. If correct, connect this to the grounding side of the fuel pump relay coil.

There, fuel circuit done!

Main relay is done in a similar fashion. The control wire is E61-9 and is Blue.

E61 refers to the 4th "magic" connector that interfaces the ECM to the real world.

-OR-

One can brute force it by using the vehicle's relays as discussed before and just ground the low side of both control coils. What happens then is that when the key is turned on the 12v gets applied to the high side of the coil and turns both relays on. This isn't an elegant solution but really insn't a problem. The fuel pump will run anytime the key is in the run position and the main relay will be on too. This is real close in operation to ECM control excluding low oil pressure and brain failure. So, that's another method.

Good Luck, -Eric

Yes, I got that far in figuring out the wiring.  I will send you the conversion list for the E61 PLUG that I have worked out.  What i am wondering is do I need fuel tank pressure and temperature (which is on the XL7 and not the tracker) to get it to run properly.  Or, do I need to install the XL7 transmitter into the Tracker fuel tank.
Thanks

You do not need those two sensors in the tank (or fooled) for the engine to run. The ECM will throw an EVAP code but operate as normal other than that. Have you tried starting it yet? You may be amazed at how little is needed for it to run. I'd suggest buttoning up all of the hardware/mechanical items that need to be done and try starting it!
