Trailer wiring,anyone know

</font><font color="blue" class="small">( Oh.. at least on 2000 GMC's with a tow package.. there is no resetable CD.. it is a large 30A or 50A fuse that goes in a holder under the hood. )</font>

Are you talking about the one you have to add in? If so, that is for the constant power supply aka battery charge. There still may be a fuse instead of CB, I'm not sure. Haven't investigated it that far.

I will copy some of my Tekonsha Prodigy stuff here, I thought You could use the same as my 98 Chevy but yours is different by these instructions.

This is what it say's to do.

95-96 All GM tow vehicles

The brake controls red (stoplight) wire splices into a specific white wire on a 10 pin connector. This connector is located to the left of the steering column. It is coming from the main loom of wires going into the instrument panel. The connector is white and is wrapped with grey foam tape; it will have two white wires exiting the connector. The correct wire is the white wire located in corner (f position) of the connector. splicing into this specific wire will eliminate any problems with electrical circuits associated with ABS or the cruise control.

Just for note. The tekonsha folks are very helpful in getting their stuff working / hooked up.

I have a couple of their Prodigy brake controllers installed and am very happy with them.

I just hooked up a Prodigy last week. I went to get one of the 7 wire connectors and discovered there is a six pin connector for use if you don't need a backup light. Now all I have to do is check out and probably overhaul the electric brakes on this ancient (1968) trailer. /forums/images/graemlins/tongue.gif

</font><font color="blue" class="small">( The problem with using that fused line is that the fuse pops when you need it most, when you are trying to suck lots of juice for the brakes. )</font>

That fuse is rated for the full pull of the brakes + a large percentage, but rated below the rating of the wire.. etc.. exactly what the fuse needs to be.

</font><font color="blue" class="small">( My brake controller diagram was pretty specific in that you weren't supposed to use a fused power feed.
)</font>

I refered to the section in my GM manual for adding the controller to the option plug under the dash. GM provided me with the fuse and a stub wire harness. The large fuse.. at least for -my- vehicle controlled controller power as well as battery power.. no CB in the path...

All i can tell you, is that the BIG fuse that GM provided me for my tow package had to be in for my controller to even turn on.. thus that tells mee that brake power ran thru that fuse. Looking at the fuse diagram on the plastic shield covering the engine compartment fuse tray, that big fuse is directly in line with battery power.. no upstream circuit breakers. Not even an ignition relay... I can't speak for any other years or make / models of trucks. I know my dodge has the circuit breaker.
