I had @Coolerman refurb my wiring harness and add a fusible link. The white/ blue wire is connected to my alternator and the solid white wire is the fusible link connected to the + battery. Where do these get connected to? Fuse block? If so where? Thanks in advance

I would google your year FJ40 and "wiring diagram" and see, later years are different

Saw your year in your signature....this link has one for a 71

FJ40 Wiring Diagrams

To lazy to buy or download an FSM or open up your FSM or PDF well then I have some pictures for you. I cannot confirm they are 100% correct but then again your probably to lazy to care.;) And if someone wants to upload these to mud please do in a post below. I'm too lazy to do it...

Thanks for the reply. I have a FSM I was attempting to reference, but I was under the impression my year (1971) didn’t come stock with a fusible link.

I didn't look at the diagram so I could be way off, but those look kind of like the wires that plug into the Ammeter on the back of the instrument cluster.

Edit: Changed the word Voltmeter to Ammeter. Thanks @73FJ40 .

Ammeter. The stock gauge measures amps.

They must be connected a certain way, check the wiring diagram for guidance.

Just to complete this thread:
The solid white wire goes to the Amp Meter + terminal and the White/Blue goes to the Amp Meter - terminal.

What wire gauge specification is the stock Ammeter wiring? Can't use stock ammeter with upgraded alt, so if using a new ammeter, the wiring becomes the constraint.

 

[Coolerman]

10 gauge is the wire size for the OEM Amp Meter to alternator (White/Blue), and Amp Meter to battery (solid White)

 

[Braden620]

So about 30 amps max on that circuit. Wouldn't work for an upgraded alt and ammeter. Would need to use a seperate ammeter and use stock wires for signal to display.
