NA to turbo swap - LA3 to PIMPXS

[slumlord]

After 10 years of the 88 TC motor sitting on a stand, I am finally putting it in my 88 Mustang LX. As I modify this car, I have taken the approach of doing things in a manner that it is easy to troubleshoot as I only did X amount of things that could have created Y issue. I also have every intention of driving this car this summer be it Turbo or NA.  That being said, I have an LA3 and have read Stingers wiring tech article and feel a swap to the LA3 would be rather simplistic but if I intend to go with a PIMP XS "at some point" or "eventually" why hack up the harness and change the pinout? Would it be better to rip off that bandaid and just go for PIMP ECU? I also have every intention of going coil on plug but again, "eventually" or just do it. I have read quite a few threads that just sound like the installer bit off a touch more than they could chew and I know if I did this in steps, it would not be so bad.  This decision could also affect which intake I run and or which oil pan as I am sure the LA3 would be much happier with the TC sensor harness, but does the PIMP XS care which harness it has plugged into it, which intake?  Does the PIMP XS need that sensor in the TC oilpan?

You're not really moving pins for the LA3 in an 88 Mustang, you're just adding the VAM and ACT sensor wires to the ECU. A PiMP would not use the VAM wires but need the ACT.

Neither ECU cares which sensor harness you run and neither requires the oil level sensor.

Coil on plug conversion is built to be an "add on" so there is no benefit to doing it all at once and it likely goes against your "one thing at a time" approach. Likely better to get it running before getting that far into things.
