Hey peeps, I'm old school forum for life kinda guy so technical stuff going in here instead of on bloody FB...

THE MASSACRE: pulling 1UZ(stock ECU) from UZZ31 soarer... shoehorn into MX83
THEN!
1JZ into same UZZ31
seems simple enough.. right?

SO THE BIG QUESTIONS:
How much of the UZZ31 and JZZ30 wiring(body) is the same?
for arguments sake, Could a factory JZ ECU loom be plugged into the same points as the 1uz was previously and work? are body pinouts the same?(same 4-5 plugs used?)
i understand that the dash config may be different(6cyl vs 8cyl) so I'm sure there would be certain things that won't line up but that what I'm trying to nut out (and I'm new to the soarer body electrics.. not toyota, just soarer lol)

Hope you can help guys(thats if we are all still on here and not trolling FB instead)

Cheers
Mick
