3 Speed to 4 Speed Overdrive Relays

As I put my BN1 back together I opted to go the 4 speed route. I have a BN1 wiring harness, which as you know has the overdrive wires under the dash. You also know that the 3 speed transmission use 2 relays and the 4 speed uses 1 relay. Do I only hook up 1 relay? If so, what do I do with the extra wires? Or do I use both relays as in the 3 speed.

Thanks for any help,
Tod
