Got a new Truck (new to me)

OK working on the engine bay wire harness to get basic things working.

Computer is plugged in and main power lead at the battery is plugged in.

Found one power keyed wire to feed the engine bay components and start keyed circuit.

Auto Shutdown Relay Plug has the power feed wire to run it all.

Ignition, keyed start circuit and ignition shut off. Temporary gauges, alternator light, engine temperature light, simple volt meter.

Alternator light shuts off when the charging system starts charging.

That is the basics on this No Computer Needed conversion.

Headlights, turn signals, fan motor, start circuit, tail lights and flashers and wipers all work now.

So far so good.

Alternator was burning out the 25 amp fuse at the + battery terminal at start up.

Turns out the 25 amp fuses were not strong enough to handle the initial surge when the alternator starts up and goes to charging.

Went to 40 amp fuses and now all is well, starts up and keeps charging as it should, without burning the fuses.

Pretty much a rough draft layout, with everything working as I have wanted it to.

Will secure things and get ready for some road miles.

Can always make it look pretty later, just happy things are up and working after all the conversion processes.
