95 s14 ecu relay goes off when ecu plugged in

[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 harness2.continuity test on all wires3.check all the relays4.fuses everything

please nico your my only hope....
