Entrophy with trinary

[redzo6]

Hello all, Well I have everything hooked up and triple checked. I am having a problem with the trinary switch not grounding out when the pressure reaches 220 psi turning the fans on.

The green entrophy wire which is attached to the blue wire on the trinary is putting out 4.5 volts (hooked or unhooked from trinary), the other blue wire on the trinary is grounded to the frame. The black and green trinary wires are hooked to compressor clutch and the other is hooked to a/c controls on the dash when power turns on.

The fans come on fine when the car reaches temperature but not when a/c pressure.
Both blue wires on trinary unhooked do not have continuity but when hooked up to entrophy wires, I get continuity.

I am so lost. cant figure this out. Thanks in advanced
