I am getting ready to install one in my 71 240 turbo. Just waiting on Pallnet to make me the SDS crank trigger bracket for the hall sensor. It is currently running on stock 77 electronics with a Vortec FMU. All the engine wiring harness is coming off, distributor , AFM, old ecu , & old transisitor box module. The crank pulley then will be pulled out & drilled for the magnets. I have to solder in the resistor packs for the injector wiring harness & try to figure out how to wire the 240 sx throttle body & the rest of the sensors. I already have a mechanical oil pressure guage but still have to wire in the 280 tach & run a new wire to the stock water temp guage & sender. I will post again as soon as I get it started.
