JZA70 to SC300 wiring
Does anyone have the wiring diagrams for both USDM Sc300 and JZA70 underdash plugs?? I can't find them anywhere.... I got a JZA70 1JZ that im swapping into a SC, got everything else finished besides the underdash plugs.....

Anyone?? I really need the pinouts on the 7(?) plugs on the JZA70 harness under the dash by the ECU... The USDM plugs shouldn't be that hard for me to find....

main reason why people don't swap a JZA70 1JZ into an SC...the wiring it a ***** and a half to work with. I have yet to find someone who has done it successfully. The body plugs on the Supra are COMPLETELY different from the newer SCs. Really your best shot is to ditch the JZA70 1JZ and update to a soarer or chaser 1JZ.

Im in the same boat, i just recently picked up a sc300 black on black 5-speed with supposedly a jzz30 1j motor harness and ecu, just to find out its a jza70 motorset. I already pulled the 2j with spun bearing out and now im stuck.
anyway i was wondering if anyone had any pinouts for jza70 to jzz30 wiring. OR some information on how to obtain a jzz30 harness and ecu..?? any help or advise would be greatly appreciated! Ive searched all over the past week and only thing ive found is how to swap a jzz30 into a ma70.
Thanks in advance!
