hey guys so i just finished droping my b18b into my Crx but for some reason my ecu isnt turning on and i cant hear my fuel pump, i tried a different ecu and still nothing...so I started checking near my fuse box and i came across a some wires that wernt plugged in but idk where they go or if they are for a relay...its a 4 wire plug with the colors--- black w/red stripe, black w/yellow stripe, black w/white stripe and a smaller blue w/white stripe and white dots....if anyone can help me I would really appreciate it

 

Make sure the engine harness is grounded at the thermostat.

 

All grounds are good but for some reason still not getting power to my ecu

 

ECU and Fuel Pump both go to the main relay.
That's a 6 wire plug though.

Does the main relay click when you turn the ignition to "ON"?

I'm going to figure that it doesn't.
My guess is that the connector you have with the 4 wires is probably for the ignition switch harness
It plugs into the front side of the fuse box

This pic shows the connector spot directly above the 15-10-15 fuses on the left

 

Ignition is hooked but still nothing and I still can't figure out what that 4wire plug goes too...I been reading on different forums and doing reaserch but nobody seems to say anything about that plug
