89FormulaLS

I am looking for wiring ideas for my 89 Formula 350, The car is completely stripped with only the rear tail light sub harness and front headlight harness installed. I am using a megasquirt pro ultimate and a 5.3L LM7 and TH400

The compenents I will need to wire up:

1. 2x Walbro 455 fuel pumps (each can draw 15 amps) - Thinking two relays and have one triggered by the Megasquirt at 100% tps
2. 2x Ford Taurus 3.8 dual electric fans (30-35 amps)- Both controlled by the megasquirt and one relay
3. Lights ( ? 10 amps?)
4. Brake lights (5 amps?)
5. turn signals (7.5 amps?)
6. Trans brake (15 amps?) - one relay - This is a trans specialties TH400 brake solenoid
7. Accessory power for Android tablet I am using for my complete dash/gauges (3amps)
8. Starter solenoid relay ( ?10 amps)
9. Megasquirt power switched 12v (4 amps)



So to break this setup down I will need a relay panel with 5 relays, and 9 fused outputs. Anything I am missing? Do i need to run a relays for lights, brake lights and turn signals?

anything such as light, pumps, and motors should use a relay as are hi current draw.
