Default Trailer Hitch Wiring, what's needed?

Sorry if this is redundant, but, my search came up empty.

What do I need to wire a flat-four connector for trailer lights? Is a "Modulite" required to maintain system voltage and not cause light-drag? Or do I only need a $20 converter kit?

Thanks,

Curtis

Are you wiring one from scratch or going to use the Subaru hitch/wiring kit?

Default Wiring from scratch

Glenn,

I would like to use a generic converter. The subaru part is $90 retail, $55 @ cost. A generic converter is $20.

I reviewed everything that you had posted on the topic, as well as others comments. What did you use to wire yours?

Thanks,

Curtis

I used the Subaru converter that came with the Subaru hitch kit. Of course, there's no real advantage in using it unless you have a TS wagon as the WRXs and RS don't have the connector.

You might find my cheat sheet is helpful in figuring out the wires to connect to anyway.

Here it is with the Subaru harness colors removed, leaving the general description and wire to tap from.

1. +12v -- connect to Blue/Red wire on trunk light (requires long wire)
2. Right Turn -- connect to LightGreen/Blue in rear RH light assy
3. Stop -- connect to White/Blue wire in rear RH light assy
4. Left Turn -- connect to Blue/Green wire in harness near rear RH light assy
5. Tail Lights -- connect to White/Red wire in rear RH light assy
6. Ground -- connect to ground Black wire in rear RH light assy

As usual, if your car catches fire, don't blame me.
