Wiring an R32 RB26 as a stand-alone motor.

[fast-datsun]

We have been supply the STL wiring service for RB motor for 12 years so you can put the motor into anything. Customers have put them into Chevy Trucks, BMW, Boats ect...... Sorry repeat!!!!!!!

Updates Z-ya ?

 

It's running. Haven't driven it yet. Sounds good, idles smooth. I wired the check engine light to the amber choke lamp in the console. I'm also wiring in a hidden kill switch. Tach isn't working, so I think I will need to make a converter circuit because the ECU probably puts out a 5V signal where the 280Z tach needs a 12V signal.

OK, I finally have the tach information. So to use the 280Z tach with an R34 ECU, you need a 1kOhm pullup to 12V on the ECU tach output. So the output from the ECU is "open collector" for you electronics geeks (like me).

I would wire the resistor into the dash harness rather than the tach harness if you can (so that you can swap tachs easier if you need to). Or just wire the resistor on the back of the tach.

Thanks again, Z-Ya! I'm in the process of swapping tach guts...
