What’s the actual color of the wiring/connector for the coolant temp sensor??? I have a mess of wiring to do and can’t find anything anywhere to figure this out
 
I believe that’s green and blue
 
Just got back to the shop my 88 fsm says green i am working on a 84 fj60 just looked at that and i believe its green also and come from the driver side fire wall groomit alone in its own split loom
 
Yes. It's on the driver's side and you will probably have to extend it. I haven't gotten around to hooking mine up so post a pic of what loom the wire comes out of when you find it so I can copy. :)
 
Hell yeah! drivers side and green AND blue? Or just green ? If I find it tomorrow I’ll post pics thanks yall
 
Yeah 4 months later And still no luck... if anyone lives in the Phoenix area and has an fj62 with the stock motor or even a completed LS swap I need your help finishing up this wiring
 
Well for starters I’d like to clean up all the wiring that’s left over from the stock engine. My turn signals/flashers aren’t working . My instrument cluster lights aren’t working.. let’s rewind a bit . I bought this as a shell , lots of missing parts . Ive been focused on getting the 5.3 in and running for the past few months . Now I’m at the point where I want everything else in the truck to work . That’s where all this wiring mess comes in .
 
If you're still looking for the temp sender wire, I just had the same problem and found the sender wire to be one large blue wire (12 gauge wire maybe?) coming out out the factory harness under the brake master. This FJ60 was previously swapped with a 305 in it and is getting a 6BT so I'm not sure if this has been moved previously but its where I found it. ground that wire and the gauge should peg out on the high end.

Hey thanks for the response. So I never ended up actually finding that wire, instead I went directly from the harness behind the instrument cluster and overlaid a new wire. I had so many random wires scattered with pins that were a bit corroded. I figured this was the best thing to do to avoid any unwanted resistances.
