Car is now running more frequently on the road and almsot ready for a nice road trip
Tach -
Now working ( It sems the Aristo Tach signal comes off a plug - II - 29 which I did not have) I pulled the Tach signal from the check connector - Pin labeled IG- ( black wire )and the tach works great.
Water gauge sender -
I broke mine and the 1JZ one was too big to fit on the 2JZ water pipe. I went to the junkyard and grabbed a couple of them from the Toyota Corolla/Camry. Same thread and the gauge works without any issues.
Hydro Fan -
Got a Camry Hydro Fan ecu from the junkyard and wired it in and the fan now spins at full speed. Now I can take the car on the freeway
Basically wired the Camry's hydrofan plug - Blue/yellow - Pin2 and Yellow- Pin3 to the Solenoid wires (Camry Hydrofan wires are slightly different color)
Wired the White/Red - (Pin 1) to the B2-pin9 ( grey) waire for power
Pin 4 - Brown = ground
and this makes the fan spin full speed once the ecu is plugged in.
I need to put a few accessories on for monitoring and tuning - otherwise its pretty much done.
