2jz swap...wiring Q???...

[DarkSupra2.5]

A big problem with splicing the 2jz loom with the 7m loom, besides being very difficult, is that the 2jz computer works in conjuction with a fuel pump computer as well. Without the fuel pump computer, the 2jz ecu won't do much.

here at least tho, you'll have the ecu pinout, i can't remember where i found the fuse box pinouts or dash pinouts, but I hope this helps a little.

so if i wanted to use the 2j ecu, i would have to put the fuel pump computer into the car aswell right?...so why is that so hard? problems with tryin 2 hook up the fuel pump computer?

don't know about that myself, i've never had the chance to do the swap, but i think if you're good enough with following wiring diagrams it shouldn't be that big of a deal. at most, you might have to make a harness to go from the fuel pump control computer to the 2jz ecu. after that, it's just swapping the 2j harness to work with the MKIII body and gauges.
