s14 ecu relay problem

[jdmwill]

ok here's the problem i made a rookie mistake and im paying for it dearly. i've done this a thousand times with out a hitch and never had a problem. i was wiring in a z32 maf in and inverted the wires. so the ecu and harness got fried. so i purchased a new 95 s14 ecu and harness installed it and nothing as soon as i turn it to ign the ecu relay goes off.
what i've done so far:
1.de-loomed the whole harness
2.continuity test on all wires
3.check all the relays
4.fuses everything

please zilvia your my only hope....
