Rewiring my 72 Powerwagon from front to back. 8 circuits or 12?

I am starting a long term restoration on this thing in stages, and first thing I need is the wiring to fix the crap the previous owner left for me as well as the problems the rats caused me after 1 year of storage in a field. My plans are to keep this thing as stock as possible as it is pretty cherry, but also make some modern updates.

So, I am getting ready to jump the gun on one of those universal wiring kits and I am trying to figure out if I want to go with a 12 circuit or 8. The stocker is an 8 circuit system. I am thinking the 12 so I can expand later on down the road, but about the only thing I can think of is a CB. So, any advice?

-Greg

get the 8 circuit.. you can add circuits by using an add on panal.. you can make 1 with a relay that can carry 30 amps and a cheap fuse block, or painless wiring makes a couple models for around $50..

Go with the 12. It is always better to have too many than not enough. Who knows what you may add later if you really like the truck when it is finished Or if you sell it and the buyer wants to add.Good selling point.IMHO.

I agree. Always leave yourself room for the next upgrade

For the money... EZwiring has a 21 circuit kit that includes things like 3rd brake light, power windows and locks, electric fuel pump, AC compressor, electric fan, and has provisions to plug into many common GM, Ford, and Mopar steering wheel harnesses, all for the bargain price of $185. For that price I can coil up the extra wires for the future, but adding cicuits to an existing harness just feels like a duct-tape patch job to me. I'd rather go overkill, then I can use any one of the extra cicuits for any one of several accessories down the road.

I just did a complete rewire on 4 tonne 1967 Bedford.. and went with a 20 circuit loom.. Needless to say, I now have a few spare circuits but little applications are already popping up to put them to use..

The spare circuits really don't get in the way.. I wound them up neatly and cable-tied them under the dash..

Also.. I bought a $120 current limited power supply to test it all with.. it takes the place of the battery.. if you short something out it trips the current limit circuit.. no burnt wires, no blown fuses.. it was great for testing.. The only thing you cant test is the cranking circuit

I also wired up a really long test lamp for testing.. an old indicator housing and 7 metres of wire for battery and earth and a pair of clamps.. it made testing a lot easier.. you can tape the light to the cowl or something and see it from anywhere.. sure beats the fiddly little test lamps.

Cheers, Dunc.

I was looking at the ezwiring kit, however, I am unsure of what it includes since the website and ebay ads are very limited on information. I found you can get their mini 12 circuit kits on ebay for $130: http://cgi.ebay.com/ebaymotors/UNIVE...m260252960708&

Has anyone used these? If so, what do they include? Ground wire? Are the wires labeled or just color coded?

The reason I ask is I came across this kit as well:

http://stores.homestead.com/ez2wire/...GTO/Detail.bok

It looks to be a hell of a lot better put together, and includes the install kit as a pdf on that page. I am leaning towards the extra few bucks as I think it will be a better product. I'll pay $60 for less of a headache.

Thanks for your help guys.

-Greg

PS Dunc: Where did you get the current limited output supply doohicky? I've read about them, but I just googled and couldnt find anyone that sells them.

I like the EZ wiring kits as well. I began selling them this year solely based on their reputation. I have never used them myself, but I know countless street rodders without much wiring experience that have.

The wire is labeled every five inches. They are color coded. The connections, alternator, turn signals, etc are GM though They do come with diagrams for Mopars.

I feel they are a good quality harness and are put together nice.

Hope this helps!

Ryan
