Honda S2000 engine installed in kit car. How do I wire alternator

I am using a Ford wiring loom and find that the Honda alternator has 4 "control" wires where as the Ford altrnator has only 2.
The Honda alternator plug cables have the following code:-
White /red
White /green
White/blue
Black/yellow +12v

Can you inform me how I wire in the Honda alternator?
Thanks

Unfortunately the Honda alternator is regulated by the ECU, which allows the ECU to intelligently reduce alternator engine loading to improve fuel consumption. The intelligent system uses an electrical load detector (ELD) located near the battery to control the alternator output voltage. A two wire alternator has an inbuilt regulator that will always generate the required charging voltage. When a battery is fully charged and the electrical loading is low there is no need for generating the charging voltage, in this situation the honda alternator will reduce the output voltage to reduce engine loading, hence improved fuel economy.

    Update: although the ECU regulates the alternator voltage it will work fine on its own. All you need to do is connect switched 12V to the black/yellow wire. The white/blue cable can be used to give you your normal dash battery light indicator, if the alternator is not generating it will provide an earth.

Wiring for trailer lights


There is usually a Kit in a plastic package that comes with the truck. You may find the kit in the Jack sleeve under the Passengers front or rear seat. This Kit can have additional Flashers that go under the hood in a relay box, and a wiring "Stub" for Electric brake controls. They fit multiple applications.

My 1999 had a connector under the dash for Electric brakes if you are going to use them. You can check for a wiring loom under the rear frame of the truck, most come prewired. If you are going to need to add the actual plug-in, the newer Ford products have a dual fixture plug which can take anything.

Tractor Supply is good for aftermarket trailer accessories and if you want Factory parts and need wiring too there are bigger kits at the Dealer. The correct gauge wire is important.

Ideally, you could find a truck in a Salvage Yard, wrecked in the front or bad engine, with the bed missing. Then it would be easy pickings to strip the frame. Really would not matter if it was a Crew cab as you can bundle the slack.

Look under your truck for extra wiring, you may just need the Plug.

Wiring towbar electrics for nissan navara d40


The best, and in fact the only recommended solution is to use a plug-in dedicated wiring kit for this car, it plugs into a grey connector on the chassis on the rear of the left hand side. this is the connector that the cars rear light loom is plugged into and the towbar loom piggybacks onto this using the same watertight sealed connectors. There is a trailer indicator warning light already built into the dash display so no need for any other monitoring of the trailer functions. This wiring kit should cost you around £40-£50 and will only take around 10mins to fit. The other alternative is to solder the towbar wires to the cars loom, but this is time consuming and may invalidate the vehicles warranty.
