Trailer Plug From Coach to Toad

I am going to be trying to clean up the plugs and get something working so I can tow my jeep.

Currently there are 2 round 6 pin plugs and a flat 4 pin.  my question is would I be ahead if I just removed the 6 pin and put in a 7 pin?

The harness for my toad is a flat 4 pin.

Thanks

Thanks craneman, I will have to get one depending on which way I go, but the plugs on the coach dont seem to be working so I will have to do something with them so if I need to replace is it better to replace with a 6 pin or use a 7 pin for a extra ground wire.

What I usually find with these plugs is a poor connection due to corrosion  or the small screw loosening.

If you have to replace it get the 7 pin as all the later accessories use it and a common adaptor for it gives everything. I wired an additional one on my coach specifically for towing the GC. It charges the Jeep and independently powers 2 rear lights I added to the toad.

Thanks, the contacts do look old, used and some corrosion and it might be easier in the long run to replace them

Thanks,  That is sort of what I was thinking, I got a harness that taps into my rear lights on my CJ5 and the only one I can get now is the tail light, the t/s and b/l dont work at the plug on the coach.

Deoxit is your friend.  I've had numerous problems that I've fixed with a quick spray of Deoxit.
If the plug looks and feels loose you can try tweaking (spreading) the pins to make them fit tighter.  Not a permanent fix but could get you going.

Thanks I think the problem is in the wiring as I am using my volt meter probes and scratching them in and not getting power from most of them when turn signals or brakes are applied.  It may be easier to just clean it up and go with new connectors.

I found, on the female 7 pin on the back of the coach, that I had to "spread" the copper contacts a bit. This created a much better solid contact with the male plug end. Before I did this I would have to rock the two parts together and also push them together and take them apart. Reliability was very spotty until I spread each contact in the female end. I would check the lights, drive for awhile, then check toe lights again and find they were not working. Spread each contact and now continuously works.

Thanks nitehawk, you are correct.  I learned that on my 5er when I was rolling along in Provo at 70 and traffic about a 1/2 mile ahead were putting on their brakes and when i got on my my dash lit up trailer brake failure, I had to stem my seat 5 or 6 times to get the pucker out of it  ^.^d

We went to the bigger 7 blade socket and plug. Much bigger contact areas make it less likely to have bad contach and the bigger plugs are easier to handle and secure.  Once it is clean use dielectric grease to keep it that way.
