okay, so i picked up a 1uz from a 93 sc400 with ecu and harness. while i was doing some research i came across some information stating that all you need to hook up to make the engine run is 5 wires? switched power to pin 2, 3 on eb2 and pin 11 on ij2. constant power to pin 4 eb1. and start power to pin 1 eb2. is this true? the reason i ask is because i don't plan on having a/c, or using any factory gauges except for my speedo. if this is all i "have" to do, my life will be much simpler when it comes to the wiring. thanks in advance for any info.
