Wiring harness

[Mischief7m]

I have a jza70 wiring harness, do i need any part of my 7mgte harness? or can i sell my 7m harness. i know i have to extend the 1j harness, but i cant figure out if i need some of the body plugs.
sorry if this has already been answered

I'm sure this has been covered alot, but yes you need the body connectors, there are four by the ecu. not the ones going to the ecu.

yes you need them. wish i knew that before i sold my harness though. :nono:
now im waiting for another one to get here, before i start on the wiring.

i need info on this too. what do you mean not the ones that go into the ecu? So i plug the jza70 plugs into the 1jz ecu?? where do the 7m connectors plug into?

The plugs you will need are for the dash harness, the ECU plugs are not touched. You don't actually need your 7m harness plugs, it just makes life easier. I was able to make all of the plugs from other toyota plugs. If you have a 90+ car, one of the plugs on the 1jz harness is the same as well.
