Ac amplifier hzj79 (1 Viewer)

[samreilly]

Hey all, just finishing up an ac install in a fj73 that is now a hzj73.

All the ac parts are from a hzj79, and I just need to know what wires/ parts to cut/adapt to get rid of the idle up function and rpm functions as it was petrol and gas swapped to diesel so the tacho doesn’t work anymore.

Part number for the ac amplifier I have is: 88650-60141

I have the loom for it as well but can’t get my head around the wiring diagram.

I’ve gone through the threads in regards to the fj60 and 62 ac amplifiers would that have any relevance ?

It’s the last piece to the puzzle
Cheers all

i think you'll need to bypass it completely unless you want to modify the circuit board itself.

pretty sure you can jump the yellow wire to the black with white wire and a/c will work, but at your own risk.

Dam was hoping it was as simple as the old fj62 board.
Jumping these wires will that still go through the cycle and not freeze up ?
