I have the attached Voltage Regulator (Toyota 27700-54040-84) I’m attempting to wire into a harness I’m building for a 1982 FJ43. For the life of me, I can’t determine with certainty what wire is what and I’m asking to prevent frying the unit.

I believe (but looking to confirm) the following:

IG = red wire
N = White wire
F = Green wire
E = Yellow wire
L = Black wire
B = Blue wire

IG N F
— — —
— — —
E L B

And when looking at a 1982 wiring schematic, do both the IG and E go to ground/earth? Asking because earlier years (1980) did not ground the IG via a condenser...so I’m confused.

u do understand that the primary color wires on the 54040 regulator side are simply the Tracer stripe wire colors on the harness side

so solid yellow = white with a yellow tracer stripe


hope that helps ..........

But to my original problem: I’m building a wiring harness from scratch because the old one was bastardized by PO and doesn’t match specs (or anything close...it had a ford four pin VR). So I’m having to recreate the wheel.

I need to determine what color wire corresponds to what function: IG N E F B and N.

alot of this depends on what alternator u are running ?

do u have a factory EWD , Both USA & NON-USA


The big Tan Chassis Body FSM has some great diagrams that cover both applications #36044 & #36044E

I’m not sure honestly. It came with the charging indicator light next to the parking brake. I’m planning on wiring it to US specs as near as I can. My alternator is a 30amp.

I’m sorry: I have a 50 amp. Here are the specs.

I was referring to your instrument cluster , regarding the AMP meter inside it

Woke up to a hijacked thread. To get us back on track, I am asking the original question in another way:

I have the voltage regulator in this picture (borrowed from another thread) I am creating a new wire harness because old one didn’t exist and I’m starting from scratch. Help me identify the wires coming out

red wire = what?
White wire = what?
Green wire = what?
Yellow wire = what?
Black wire = what?
Blue wire = what?

They are what of the following choices?

IG N F
— — —
— — —
E L B

To answer any other questions, I have a 50 amp alternator and instrument cluster. The alternator has E F N and B connectors with an external voltage regulator pictured.
