Mike, It is plug and play. The 8 pin connector, which has your tender and engine marker lights also has 5 additional outputs. 2 ditch, 2 mars and a beacon.
Each output can control 2 bulbs normally. Except the beacon which is always a flashing LED when used.
So you have 3 double bulb connectors for your driver lights. 3 of the 4 Ditch/Mars are set for constant on by the sound file and run those lights.
In your case your not doing a traditional upgrade, you just installing a PS-32 board with 5V connectors and removing the battery and wiring, and replace the speaker with a 4 ohm. G
