MA70 to JZA70, Need Help

[Brendan-m2]

Hi Guys, Before anyone flames me I have searched everywhere for this information, multiple forums and all links I have found are dead.

Basically I'm after some information about rewiring the plugs that come into the cabin from the 1JZ engine into the MA70 wiring loom, the 1JZ I have is from a JZA70 Halfcut, there are 4 plugs on the MA loom and 3 on the JZA loom, the MA70 is a 1989 Model, will post some pictures of the plugs up in a few hrs when I get home from work.

If anyone has any of the diagrams for wiring these plugs could you please post them up for me.

Thanks for any help.

Brendan

Here are the JZA Plugs:

ah yes, you have a 89 ma and a 90+ jza. grab a ewd, some coffe and start repinning the connector. Most are colorcoded the same, just go one by one.

Ok, here are the plugs from the 7M wiring loom:

The diagrams on how to do it is somewhere on this forum and supraforums. Its really confusing until you start doing it.

Trust me I had this problem til I kicked my ass down to doing it myself. Once you start working at it you will see its all laid out pretty easy if you have the rewire diagram. Again its on both of the forums somewhere on one of the stickies.

Good luck dude!
i have been there. The damn 89's are the worst for wiring, because they changed so much that year and it wasnt standard.
