Just bought a KE70 Wagon with a 20V as a project thats been half done.

I kind wish I had done the conversion because at least then I could've marked down every wire I pulled off as to where they all go.

But this is what I bought into. I'm a little confused, the battery tray in the engine bay is goneski's,

and I take it that somehow the fuse box mounts off it? (1st ever KE70 that I've looked at)Coz its just dangling.

Being that all the starter and battery wiring is also gone, I have nothing to go off.

I need a hand with identifying what some these wires are. Can anyone please help me.

 

#1 These 4 that come off the main harness from the inner guard and head into the fusebox, Red/White, Green/White, Purple and Black/Brown

 

#2 This Plug that runs of the fusebox?

 

On the 4AC AE86 sprinter that I wired up AE82 4AGE the Black/White was starter (I used it as starter sence for the ECU) is that the same on KE70?

 

#3 Also, I need to ID the ALT wires from the fuse box.

I take it that the thick White is Trace and White/yellow is Sense....

But I looks like there is no Ignition (for 20V ALT)? Do I just run that off a relay? Or am I missing something?

 

I have more questions, but this will do for starters.

Any help would be greatly welcomed as I'm doing this on a budget and I'm going to have to do all the wiring myself.

Thanks,

Al.

#2 is power feeds to your fuse/relay box. Must connect to the positive side of your battery via a fusible link.

 

Yes the black/white is your start signal wire to the starter solenoid.

 

#3 the thick wire is the charge wire to the B+ on your alternator and the other wire is the charge light.

 

3 wires to the denso alternator for your regulator should be;

 

Ignition - Ignition switched 12v

Lamp - From your the smaller yellow wire in your third photo

Sense - Connects to the positive side of your battery.

Thanks heaps mate!

What size fuse do I use for the #2 Power feed fuseable link?

 

Is picture #1 wiring aftermarket? Just the the KE70 wiring diagram I have has no purple wires?

probably be easiest if you can find an original fuse link at the wreckers otherwise if you get stuck let me know and i can make you one up out of proper fuse link wire, but plug on the fuse/relay box will need to be changed to accomodate.

 

i can't see what the other wires are for in my diagrams, but if you get stuck let me know and i'll look on my rolla to figure out what they are.

 

most stuff on that side is ignition supply for idle control and fuel solenoid on the standard carb...

medicine_man, you might be able to help me, this picture shows a factory loom running across the engine bay against the firewall (don't thinks its spose to be)

4#

On this loom is the water temp and oil pressure (found these no problems)

There is also 2 Red/Blue wires?

5#

And this plug on a think black wire?

6#

Enlighten me please?

Red/Blue are the reverse light wires, not sure on that black one though.. does it come out of the same harness?

Reverse wires? OK, I never would have guessed that! Thanks man.

Yeah mate, that thick black wire and plug comes off the same loom?

Splits just before the Oil pressure and Water temp.
