5m-e to 2jz-ge wiring help.

[Admiral coFF33]

first with the fuse box wiring do you have both sides to the IG1 plug from the jza70?

next you need to locate the MA61 version of the MA71 connector C1
shown in this link http://www.1jz.com/tech/docs/wiring/EA21989.pdf

cut the jza70 IG1 wiring off about 15cm after the plug on the fuse box side
Join pin 1 B-Y to the correstponding ma61 B-Y (note this might not be the right colour you need an ma61 wiring diagram to decipher what does what)
join pin 2 B-O to the correstponding ma61 B-O (note this might not be the right colour you need an ma61 wiring diagram to decipher what does what)
join pin 5 B-O to the correstponding ma61 B-O (note this might not be the right colour you need an ma61 wiring diagram to decipher what does what)

In this Did you mean the EA2 (round style plug near the fusebox ? ) as the IG1 connector is in the ECU area .... or so i thought?

make sure that the jza70 alternator wiring runs through to the alternator via the engine loom
if it does proceed to join the following
pin 10 to the pin 2 (check with an ma61 alt pinout) this should go to your ma61 dash batt light
pin 11 to the pin 1 (check with an ma61 alt pinout) this should be going into the fuse box and with a battery connected should read 12v at all times
pin 12 to the pin 3 (check with an ma61 alt pinout) which should get 12v with ignition on and 0v with ignition off...

With this, Did you mean leave the standard 3 pin plug (engine loom side) connected to alternator, then splice in the MA61's 3 seperate body loom alternator wires? can you explain a little better on what you mean....... I do understand there is MA61 Alternator 3 pin that runs with the AFM wiring on the body, and i do understand the 1JZ has its own , but what do you mean "join the following" ???

then you need to go to under the dash and get the jza70 IH1 plug and find the equivalent version from the ma61

then you can start connecting up those bits... the big thick B-W wire should go to your starter motor and the big thick B-O should go to injectors coils ecu ignitor etc etc
thats all i have time for at this point but its not too difficult

I thing The IH1 plug under the dash, The B-W (pin 10) needs to be connected to the MA61's B-W fat wire off the dash loom, and the 2 x B-O (pin 9 , 14) need to be connected to a IGN 12v+ source for injectors/ignitor, Then there is the 2x B-R (pin 7 (fat) and pin 3) which according to this guide :

http://www.1jz.com/tech/docs/wiring/IH1(90-92).pdf

Are for pin7: COR #2 and pin3: FP REL & RESISTOR

yes sorry EA2

by join the following i basically mean chop off the ma61 3 wire alternator plug and join those three wires to the corresponding 3 from the EA2 1j plug...
the only catch is you need to make sure that from the EA2 plug the 3 alternator wires on the 1j loom go directly to the alternator...

I thing The IH1 plug under the dash, The B-W (pin 10) needs to be connected to the MA61's B-W fat wire off the dash loom, and the 2 x B-O (pin 9 , 14) need to be connected to a IGN 12v+ source for injectors/ignitor, Then there is the 2x B-R (pin 7 (fat) and pin 3) which according to this guide :

this sounds about right however i have not played with ma61 before so cannot be 100% sure...

Ma61 alternator wiring is not part of the engine loom, It's part of the body loom and stays when you take the 5me out. You can plug it straight into the altenator if the plugs match, if not swap the plugs and done

is the ma61 alternator in the same location as the jza70 one?

i thought it would be the same as a 7m and alt would be near the battery with a short cable?

if this is not the case and it sits on the drivers side down low then thats an added bonus

EDIT: just looked at some 5m pics... that makes things easier... do as wilbo said... his correctness never ceases to amaze me

[Admiral coFF33]

Ok, so i no longer need to splice the alternator wiring into the EA2 plug, i just run the MA61 body loom plug (that was on teh 5MGE alt) to the 1JZ alt and forget about the engine loom plug that was connected to the 1JZ ALT

[midnight_purple_GA70]

7M.JPG

See the attached image... this should make it clearer...

wiring diagrams youve been looking at are for ma71
so the 7m has the alternator in the green oval and connects straight to the fusebox and body loom

your MA61 should previously of had the alternator plug somewhere over in the region of the blue oval (obviously the lower half of the motor)

this is the same location as the 1jz so it should be able to be plugged straight into the 1jz alternator

the reason for joining it at the EA2 plug is purely due to the 1jz alternator wires running via the engine loom to that point

[Admiral coFF33]

i see!!!!!!!

so im right in saying original 1JZ engine loom Alt plug is now void, and MA61 body loom plug is used.

Excellent.

Now to focus on other fusebox sections which i have ZERO knowledge about.

Ok 3 pin alt plug done. that was easy,
Now
The EA2 plug connects to the big fat grey round plug near the ignitor. Im guessing this runs to the fusebox. as

B-R (fat)
B-O (fat)
B-R (normal wire)
B-Y (normal wire)
Are all power wires from memory.

But around / underneith the fusebox i cannot find the wires to "matchup" with these as per Midnight Purple said above....

http://www.1jz.com/tech/docs/wiring/EA21989.pdf

This diagram shows that :
1: Needs to power the EFI relay in fusebox (i dont know how to do this or what the EFI relay is, apart from the bulb type relay in the box thats metal)
2: Needs to power the EFI relay in fusebox #2 (i dont know how to do this or what the EFI relay is, apart from the bulb type relay in the box thats metal)
3: n/a (dont have hydro fan)
4: n/a (dont have a/c)
5: Needs to power the EFI relay in fusebox #2 (i dont know how to do this or what the EFI relay is, apart from the bulb type relay in the box thats metal)
6: n/a (dont have hydro fan)
7: n/a (dont have a/c)
8: n/a (dont have a/c)
9: n/a (dont have a/c)
10: n/a As im using the MA61 body loom for alt (original wiring)
11: n/a As im using the MA61 body loom for alt (original wiring)
12: n/a As im using the MA61 body loom for alt (original wiring)



So out of this entire 12 wire plug, i need to use 3 wires?! WTF? , I mean, thats cool, but how do i connect those 3 awesome wires to the "EFI relay" ??? Can someone take a pic ?

Or am i meant to be looking like :

[midnight_purple_GA70]

i would assume that somewhere in the engine bay there near the fuse box there used to be some plugs that would of pluged into the MA61 engine loom?

finding those would be the best point of call...

in that wiring diagram for EA2 it shows the MA71 connector C1. you need to find this connector in the MA61
not sure if it will look the same or not though...

[Admiral coFF33]

Ive had a look, and all i can find in that area regarding "some plugs" from the original setup 5MGE, is the Green and yellow 2 pin / 1 pin plugs (3-4 of them) that were accociated with the 5MGE Coil setup that powered the dizzy.

[CrUZida]

B-R (fat)
B-O (fat)
B-R (normal wire)
B-Y (normal wire)
Are all power wires from memory.

B-R (fat) is +B input
B-O (fat) is MAIN relay output (powers injectors, coils, ignitor)
B-R (normal) I didn't use
B-Y (normal) Is trigger to EFI relay
B-O (normal) Is trigger to MAIN relay

[CrUZida]

And dude, use this to work what wires are what in the MA61 fusebox.

HOLY SHIT

GOLDMINE!

that one is much better for information clear and concise

should have it up and running in no time with that one
