Chuck: Don't buy cube relays with a diode across the coil inside the case or you will be back to square one asking how to hook it up.

Mine are wired just as Richard (DML)has suggested. I have a 6 relay block in the electrical panel for the engine controls. 2 relays for the jakes, 1 relay for the tranny cooling fan. 1 for the electric priming pump, and 2 spares.

This block (from Ebay) uses the plug in type Bosch relays or just use terminals. Any auto parts store will have these relays. If one should die just pull it and replace it, but haven't had any trouble since 2000.

No diodes in the cube relay, no problems either.

I wired this way because it's a long way from the dash to the engine and I was afraid the voltage drop would hurt the jake solenoids.
