Rb wiring issues argh!

Okay, heres the deal i bought an rb20 and the wiring was horrible but was told it ran, so i plugged it all in and it wouldnt start, no power to the coils or injectors.

So i tore thd harness completely down and depinned everything i dont need and a lot of wires are cut and its just bad so im replacing a lot of them.

Now here is the issue, i wanna make sure everything works before i go any farther and here is how i have it wired in.

Eccs goes to orange pin 16, red wires are together and go to 12+, and the other pin on the relay go to the white/black wires that spread apart and go go the cas and pins 49,109,58.

Coil relay goes orange pin 16, than to coilpacks, 12+, than ign source.

Than i have pin 45 to switches 12+

Problem. The eccs relay wont click, tried two ecus and multiple relays. If i ground the orange wire the relays click, but it wont send a ground from tye computer. Its like it wont turn on. I checked the grounds theyre grounded to the intake. Any ideas would be appriciated i really am stumped atm
