I guess I need a Modulite?

[SeaKaye12]

Hi,<br /><br />I'm about to wire up my old 1993 Camry for a trailer. I thought I could just splice into the wires going to the tail/brake lights.<br /><br />Seems that I need a "black Box" gadget that costs about $40.00.<br /><br />It takes a direct feed from the battery.<br /><br />Do I really need this? It seems that the consensus of directions at the various trailer-hitch websites indicate that it's essential... I really don't understand why though.<br /><br />Thanks for reading, Chuck

Re: I guess I need a Modulite?

Your car uses 2 Seperate Circuits to power the Stop lights,+ the Turn Signal lights,.........<br /><br />Trailers use the Same Circuit for Both the Stop,+ Turn Signal lights..............<br /><br />Without the Box,.........<br /><br />You'll have Either your Stop lights,...... Or the Turn Signals,..........<br />But,.....<br />Not Both.......

There are some that only wire inline with the lights, and do not take a feed off of the battery. The ones that take current directly from the battery will result in brighter lights.
