alright, so I've put everything together and it sitting pretty. It'll crank and crank but I'm not getting any spark. What are some common problems?

I modded my wiring harness myself and I followed the directions from FRS
SR20DET Swap Engine Harness Wiring Diagram Guide SR SR20 (http://www.frsport.com/SR20DET-Swap-Engine-Harness-Wiring-Diagram-Guide-SR-SR20_t_26.html)

I'm thinking I wired something wrong. On the last plugs that plugs near the battery, it says

Black / Red Black / Red stripe Main ignition power
Blue / Red

Does that mean that the blue/red connects to the black/red wire? I didn't connect it to anything since it didn't have a wire color to correspond to. I'm assuming this is where I went wrong?

Just double checking, I don't want to hook 12v up to the blue/red and have something get fried

also, it looks like there are two blue/red wires. One is thicker and one is your average wire gauge. Which do I connect to the black/red? Both? I connected the thick one first, then the skinnier one, and I got nothing. Still just cranking.

nevermind. I wasn't getting fuel either and it turns out that the ECU plug wasn't in all the way. Or something happened when I unplugged and replugged it. It works now.

I must say, WOW, what a difference when compared to a shitty SOHC
