RB20det / RX7 - wiring

[bentleylb]

Hey guys,

looking for some help here. I have installed the RB20det/ trans into my 1982 rx7 and am having trouble understanding how to get power to the RB20 wiring harness. I am quite new with wiring as you can probably tell. I've used the rx7 harness for lights/dash, fuel pump, ignition etc. I have my main power running to the starter and a relay to the 7's harness. The oil pressure sensor wires and alternator wires were cut and I'm assuming the harness gets it's power from the power wires via the alternator. If I get some help I will surely post some pics.

LB,

The 2 green relays near the ecu need power. I think one is for the ignition and the other is for fuel injection. That's about all I can remember, good luck.

Still having trouble,seeing as I have wired my starter to the Rx7's ignition. I put 2amps to the red black ignition and have ignition but the injectors aren't firing? Do i need to wire the Ignition witch start signal number 43 on the pin out for the injectors to fire?

big gray SQUARE plug give the LOWER 3 pins power and it should start right up. this plug is on the same harness as the maf, and o2 sensor.

Didn't work man, not sure what's going on. I do have power going to Black/red and White purple on that plug though. just tried ecu memory and neutral switch with no luck.

Actually I put the injector light after trying the other pin on that rectangular plug I think ECU memory and it lights but has a random pattern, I am assuming it's a ground from a dash plug that I haven't seen yet? someone help please.
