Question:

I have a 93 chevy 1500, 4 wheel drive, 5.7 L, that has a factoryI think installed flat four trailer wires on it. I have a trailer with a 7 bladed wiring harness and brakes. I would like to confirm that I need the following for a complete install with brake control: 90185, ETBC7, and 3025-P.

You are correct, you will need the 4- and 7-Way installation kit # ETBC7 to install a brake controller on your 1993 Chevy K1500 with the 4-Way flat connector. But you will not need harness # 3025-P because there is no where to plug it in on your truck.

The original Prodigy brake controller, 90185, is a fine controller but lacks some of the features of the P2, # 90885. The Prodigy has a limited range nose up or down it can be mounted and it is not compatible with electric over hydraulic braking systems. The P2 can be used with EOH systems and can mount a full 360 degrees in the direction of travel. I have linked a video review of the P2 for you.

I have also included a couple of links that show and explain the ETBC7 installation for you.
