Need help with JZA70 harness to JZZ30 ecu patch harness

[oowee1jz 0]

I'm in the process of making a patch harness for a JZA70 harness to JZZ30 ecu, and I have a few questions. On the pinout diagrams that I used, there were slight differences to what each pin is abbreviated to, for example PM is map sensor on the JZZ30 diagram and PIM is map sensor on the JZA70 diagram so I want to make sure that these are correct.

 

PM on the JZZ30 ecu is same pinout as PIM on the JZA70 ecu

VCC on the JZZ30 ecu is same pinout as VC on the JZA70 ecu

EVP PAG on the JZZ30 ecu is same pinout as EVP on the JZA70 ecu

 

Second, the JZZ30 ecu has an extra ground called E11 that the JZA70 doesn't have. Do I just splice into an existing E(x) ground?

 

And third, where do the FC and FPR pinouts on the JZA70 ecu and PFC and D1 pinouts on the JZZ30 ecu go?

 

So far I was able to match up the following pins on both ecus

 

HT

ISC1,2,3, and 4

#10

#20

#30

VF

IGF

IGT1,2,3,4,5, and 6

E1

E2

E01

E02

THA

THW

OX

KNK1 and 2

TE1

TE2

TT

VTA1 and 2

IDL1 and 2

G1+ and -

G2+ and -

NE+ and -

EGW

CCO

BT

BATT

M REL

W

ELS

ACMG

SPD

STA

+B

IGSW

STP

NWS

 

here are the diagrams i used

 

jzz30

 

jza70

 

 

I would like confirmation that I am on the right track before I start soldering, thanks

dude, this is all covered in the wiring thread.

yes

 

and don't worry about the fuel pump computer, it's just a timer / voltage dropper / motor exploder. you just need a relay to run your pump.

 

serious, go to the wiring thread now.

i just jump fp to +b and it works fine. btw this is on a mk3 not x-chassis

 

thanks apxhero
