3 pages?? wow you gotta be getting close wannroam.

Hubby is not arguing with me - he says there is no way that a "plug" in adapter will convert 4 wires to the 7 way without him actually having to wire something.

Can someone tell me the exact thing that we need?

you need an adapter that takes the separate turn signal voltage from the tv and sends it to the trailer, without letting it come back and back feed to the tv brake lights. i think it uses an electrical 'valve' called a diode.

Light Converter w/ 4-way Flat Plug (for vehicles with separate brake light and turn signals) DT119130...$21.95

Is there a "known good" trailer available that you can connect your tow vehicle to? Or for that matter another TV that you can hook to your trailer. This could save a liitle time in determining if the problem is with the TV or the trailer and keep you from barking up the wrong tree.

I don't have the tv light problem; that was another post from someone else.

I think that we have the light issue solved we just need to have the correct connection to transfer the 5 way plug of the truck to the 4 way plug of the AS.

Rickys got the part, just have to cut the flat plug off and wire it to the truck between the lights and the 7 way. It should come with instructions and just test the lighting before you button it up.

That is the converter thing I was talking about last night Wannroam. I was wondering if you got it yet. I hopefull you get it on the road, here. I predict a test drive here real soon.

wannaroam · 09-01-2008, 11:39 AM

Ok, I am on my way out to get one........cross your fingers.

mustang · 09-01-2008, 11:59 AM

Good Luck.

May sound stupid, but is the tv running? Some vehicles have no brake lights without tv running. Rest of lights may work. Shot in the dark...zz

wannaroam · 09-01-2008, 01:44 PM

And on to the next problem....

Right now the center of the 7 prong on the trailer was wired up for the new electric brakes.
Where do you then put the brake wire coming from the truck?? A flat 5 has no spot for a brake....

mustang · 09-01-2008, 01:53 PM

dont run the electric brake controler thru the device it is only for lights

wannaroam · 09-01-2008, 02:27 PM

then how do you get the electric to the brakes?

69AmbassFl · 09-01-2008, 02:46 PM

are you still using the 7 pin connector? Do you have an electronic brake controler mounted under dash? The center pin is usually wired for the battery charge from the tow vehicle,but doesn't really matter. The electric brake are controlled by a controller and is wired from it to the connector through a wire ran from inside the veh.

RBolton · 09-01-2008, 02:58 PM

I think this device is meant to be wired between the tow vehicle rear lamp wiring and the 7 way connector on the tow vehicle. It provides separate wires for the signals and the brake lights. After wiring your tow vehicle rear lamp wiring into the side of the converter with five wires, cut off the four way plug and connect these wires to their corresponding terminals on the TV seven way connector. You will still connect your tow vehicle to your trailer via the 7 way connector.

I think there is only about a 50/50 chance that this is your problem though. That is why I made the earlier suggestion that you find a donor tow vehicle to make certain that the trailer wiring is correct.

Your husband is right that he cannot install this converter with out actually having to wire something. Good Luck

mustang · 09-01-2008, 03:10 PM

You put the devisein line. The light wires run thru the device like the schematics say. and they come out the other side on a flat plug. Now, Your 7 way plugin on tow vehicle will either come with the flat plug also and you simply plug them in together or you have to cut the flat plug off the device and connect those wires to your 7 way plug in. You simply run the barke controller to the proper wire on the 7 way plug. I hope that makes sense. It should ahve come with a wireing diagram.

mustang · 09-01-2008, 03:12 PM

If you have antilock brakes you must have one of those. I havwe always been told.

69AmbassFl · 09-01-2008, 03:12 PM

RBolton is right on the connection process. I looked at wiring diagram of the veh you have and you do have separate circuits for brake and turn lights thats why you need the convertor. If hubby has a test light wiring this in will be a breeze. Hit turn signal and hit each pin in the 7 way till you find the one flashing. Cut the wire and insert the corresponding wires from convertor. You can bypass the running light circuit if the running lights are working correctly now.

I wish you guys where closer I would shoot over and help you. It is pretty simple just intimidating

wannaroam · 09-01-2008, 04:52 PM

mustang - I sure wish you were close too!

I am including some pictures this time.

As per the instructions on the Prodigy controller he wired the blue brake line into the 7 way plug on the tow vehicle. He would be all set to just plug this into the trailer but for the original problem - the GMC uses a separate line for the brake (stop) light and the AS does not.

If we add the converter as suggested the tow vehicle side is a 5 flat plug which means brake, r turn, l turn, running, and ground so what do you do with the brake blue line??

Right now he has the AS wired as follows:
r turn/stop
l turn/stop
clearance
back up
ground
electric brakes

Do they make a 6 flat converter?
