S14 SR into S13 wiring problem...

[sil8y-X]

Hey guys, just wanted to run my problem by you guys to see if anyone else has had this problem. Anyways, I've got my SR swaped in and my harness ran to the engine, dash, ecu, etc. Everything seems to be wired correctly and the motor will turn over. The problem I am having is the ECU isn't getting power. The Black/white wire at the SR/KA connectors that run in the engine bay isn't getting any power. To my understanding this black/white wire is for the ECU power. Also, there is a red/black wire that is for the ECU relay. Now, when I unplug the connector and touch a test light to the prong for the ECU relay(grounding it out) I can hear the ECCS and fuel pump relay's clicking which is telling me that it's powering up the ECU. I've looked over the harness and made sure everything is plugged up. The only problem I see is the ground wire that runs down by the altenator and is supposed to be bolted on the back of the altenator isn't bolted down. Would this not allow my ECU to be powered up? Also, the only thing I have wired up under the dash so far is the ECU, ignition, water temp, and ground for the dash. Unless S14's are different than S13's that is all I really need to have connected to get her up and running. If anyone can be of any help it would be greatly appreciated.

Also, i've tried searching for the EXACT differences between wiring up an S13 and S14 harness but have foung nothing. It seems not too many people are doing S14 swaps.
