1990 Nissan 300zx, Keyless Entry, Remote Start

ok..Connecting a keyless entry and remote start to a 1990 Nissan 300zx, previously installed was a Viper alarm and remote start that we removed. We are now installing an excalibur al-1851-edpb with 2-way pager. ISSUE: Lock and unlock will not work to save my life, 2 relays are installed, i hooked the set up to a power inverter and tested the set up, and it worked perfectly. but once its installed in the car wont work at all. All wires are connected and working, power is going everywhere it should and grounds are in place. Any help here? maybe i missed a wire or something this is the first time i installed in an older vehicle.

That year aftermarket actuators have to be added. The system is a 2 wire reverse polarityTed

Driver's door only if it's the same as UK spec.

From what I remeber you one need one actuator in drivers door wired for five wire revers polarity

You remember correctly. OP, add a DEI 451. There's either one of those or two relays firing an existing aftermarket actuator installed with the earlier Viper.
