Holley TBI wiring problem

I'm putting a Holley TBI unit w/ portmatched Edelbrock manifold on my 90 Sierra, I noticed that the Holley unit has a connector that has 4 black wires going to the injectors while the stock unit does not have the same connector & the wires are color-coded from the wiring harness to the injectors, has anyone dealt with this problem before, me & my buddy are going to splice in new connectors if their isn't an easier way. But if their is please tell me
